Hello,
I am wondering if there is a way to solve a virtual memory error? We randomly get the following error when trying to run sycn over the http websync. Some clients have 512 MB running sql express, others are full instances that have 1.5 GB.
The merge process could not allocate memory for an operation; your system may be running low on virtual memory. Restart the Merge Agent.
I have a SSIS package that is constantly running out of virtual memory, right now I am on a development server, running only this package. The package is moving data from one table into another on the same server in the same database. The server has 3 Gb of memory and is only running SS2005 and SSIS. I am a local admin on the server and running the package through BIDS, once again for our initial testing. I tried setting the property BufferTempStoragePath to our E drive so it can utilize the 100 Gb of free space we have but that doesn't seem to work either. I have also tried setting the MaxRowSize to many different values to no avail. I am constantly getting an error, see below for exact error, when it gets through roughly half the load. Moreover it reports this error about 500 times in the progress report if I let the package run to completion. Finally, when all is said and done the package has moved the data successfully but the package always shows as failing.
I have googled continuously on this problem but have not found a resolution. I did see on a post here where it was recommended to run the package out of process, however I don't see the benefit at this point when this is the only package I am running. I also don't understand why it would report the error so many times and fail the package when it is completing successfully? Source and Destination have the same number of records at the end of the task. Could someone please try to make sense of this.
Getting Error:
[DTS.Pipeline] Information: The buffer manager detected that the system was low on virtual memory, but was unable to swap out any buffers. 4 buffers were considered and 4 were locked. Either not enough memory is available to the pipeline because not enough is installed, other processes are using it, or too many buffers are locked
Any help would be greatly appreciated.

I have a sbs 2003 sp2 server running exchange 2003 sp2 it was running fine until one day I got this low virtual memory error, I checked the memory usage in the task manager and it is using 7 gigs of virtual memory, I increased the max size from 6 gigs to 8 gigs just to see what happens and now it is using 9 gigs of virtual memory. I don't have any clue as to what the problem is! Please Help!!!
View 1 Replies View RelatedI am trying to undertstand how does sql 2005 decide how to use the memory.
Does it use RAM first than the virtual memory or does it decide what to use conditionaly?
Anybody have an idea? Like if the table is really big does it put half
of the table to RAM and the other half to virtual memory ?
We have a Server that is set to use 80mb of a 128mb machine. The machine is also set to use up to 300mb of Virtual memory as needed.
After running for 10 days, we got the message "Low on Virtual memory". We did some looking and found SQLServer was using 300mb between real and virtual memory.
So the question: Is there a manual method to get SQLServer to release extra memory with out stopping and restarting the service?
I have two instances of SQL Server running on my Development machine.I am having some performance problems and while investigating theproblem I saw with the Process Explorer form Sysinternals that bothinstances consume each 800 Mbytes of memory!I experimented with sp_configure and by giving both instances a fixedmemory size. Both methods do not seem to have any effect.Can anybody explain me why SQL Server is using so much memory?Thanks for any information.Evert WiesenekkerPSBesides the northwind database I only have one simple extra database(70 Mb in size) installed.

for the last six months or so my pc has been shutting down all applications for no apparent reason when a 'low virtual memory' bubble appears. I have removed dozens of items, such as games, image editos; all programmes that require a lot of memory but it is no good. Every 40mins or so the pc decides to shut everything down and where it is impossible to start any further applications, unless I log off and on or shut down the pc myself. I really am fed up with this, its so annoying. Is it because of a virus or do I still have too much on my pc?

Hi,We have a prod server running on SQL server 2000 64 bit. It is a4cpu server with 16GB of RAM. we have a maxmemory setting of 15.5GBfor sql server. Inspite of 15GB being available for sql server, itstill uses paging file space, a lot. When looking thru task maanger wecan see sql server using 15.5GB of Memory usage and 22GB of Virtualmemory usage. I don't understand why it should even be using closer to7GB of Paging space, when it has so much memory. How does SQl serveruse Virtual memeory vs Physical memory?HAs anyone seen this before.ThanksGG

Local SQL 6.5 SP4 on a Windows NT SP4 workstation (Pentium 350 / 128 MB).
SQL server has 32 MB of RAM. It starts well but begins continuously eating up virtual memory by 16k blocks in a second,
until it takes all virtual memory.
Server's shutdown generate following error in Event log System section:
Event ID: 7011
Source: Service Control Manager
Description: Timeout (120000 milliseconds) waiting for transaction response
When I start Server from command prompt with -f switch, it did not eat virtual memory,
and did not generate any error in Event log at shutdown.
Many thanks for any help.

Hey,
I have a large set of data that I need to match against another large set of data. The reference table has 9.8mill rows and my input has 14.6mill rows. I started with a new project. I added my connection, then a task to clear the result table, then my data flow, then my OLE source, then my Fuzzy Lookup task, then my SQL Server Destination. I set the connection of my OLE source and set the query to pull the data. Then I set the connection of my Fuzzy Lookup task, set the reference table and told it to create a new index (the problem also occurs if I use a generated index) and then set up the matching criteria. Then I set the connection and destination for the SQL Server Destination.
After setting all this up, I hit Run. The thing ran great until ~ 800k rows and then it failed. I ran it several times and it always failed right around 800k with a message saying there was not enough space and then an error with buffers being passed to the Fuzzy Lookup component. I opened Task Manager and watched the resources as it ran and was amazed at what I saw. The Fuzzy Lookup component eats up every bit of Virtual Memory available and when it can't take any more, it errors out. I tried setting the Max Memory setting on the component and it seems to have no effect. I also played with the buffer settings on the data flow task to no avail. I even went as far as to put an identity on my input table and create a function that outputs selects that use a between on the identity to break the data into 600k chunks. I set up a ForEach component and DTS variables, but the Fuzzy Lookup component does not free the VM after the iteration of the ForEach component!
I ended up running each chunk of 600k one at a time. I have to automate this for the future, so I need a solution. Does anyone have an idea for me?

We are running Sql Server 2000 Enterprise Edition SP4.
The server has "frozen up" now for the second time in 2 weeks.
What happens is sql server literally dies, you cannot even connect to sql server, but it is running.
What we see are inssuficient memory erros in the event log and the following in the sql log:
BPool::Map: no remappable address found. 2007-08-1
Dynamic Memory Manager: Stolen=92810 OS Reserved=1
Buffer Distribution: Stolen=109139 Free=700 Proced
Global Memory Objects: Resource=1346 Locks=77
All i can find on the internet related to the error is that you must apply SP4 but we already have.
Can anyone help on this issue ? When this happens again how do we diagnose since we cannot even connect to sql server? This is 2000 so no DAC.
The server has 16 Gigs of ram is awe enabled and sql server is allocated 12 Gig. So i am having trouble figuring out what is "stealing" the memory.
Any ideas ?
Thanx

Here's the deal.....
I was converting a lot of MS Access records to SQL Server (almost 500,000)
and about midway through I got the old MSACCESS.EXE Not Responding. A few
more times through this and SQL Server informed me that I was running out
of locks. I upped the locks from 5000 to 20000, and retried it. I am now
getting errors like "There is insufficient system memory to run this
query". I receive this when I attempt to look at tables, devices, etc. In
SQL Enterprise Manager. I am also not able to run the sp_configure command
or choose configure by right-clicking on the server in Ent. Mgr. I am
running SQL Server 6.5, SP4, on a dual P200 with 256MB RAM. Any help would be
incredibly great.

Post installation of Hotfix Update 8.00.0679 (for the slammer worm) we've encountered this error on our production server "2003-02-13 09:54:17.14 server Error: 17882, Severity: 18, State: 1
2003-02-13 09:54:17.14 server Error accepting connection request via Net-Library 'SSNETLIB'. Execution continuing..".
This appears to correlate with attempts to access our SQL7 server, which was also patched for the worm (Hotfix 7.00.1030) via any query analyzer linked server reference; in fact the linked server attempt fails on a 'general network failure'.
On the SQL2000 side, the SSNETLIB failure is followed by failures in "Stored function 'xp_enumerrorlogs' in the library 'xpstar.dll' generated an access violation" and then all backups fail on memory allocation failures and major database selects of 100K's records fail on "unable to allocate thread".
Anyone have any thoughts or experiences germane? I'm about to undo the security patch on both servers.
Thanks,
Al
I'm currently experiencing major problems with SSIS when opening and editing large .DTSX package files that contain Exec DTS 2000 Tasks which have the package data loaded internally. I have no issues if I point the task to a .DTS file, or to an actual DTS package on a SQL 2000 server - but if I load the package internally then once the underlying .DTSX file gets over around 17MB or so in size (which doesnt take long making a few edits to even fairly simple packages now and then), I start to experience major issues with VS/BIDS 2005 crashing randomly when I try to perform any action with the package (open, save etc). Things like OutOfMemory exception errors, followed by the properties of Exec DTS 2000 task being deleted, and also sometimes accompanied by messages about the application not being installed properly.
Again its ONLY when the underlying .DTSX file reaches a certain size limit, and only when I've got an Exec DTS 2000 task with the package loaded internally. I've replicated the issue using several different package files on several different machines (even on servers with lots of memory, fwiw).
Can anyone out there help me with this? SSIS - namely SSIS Exec DTS 2000 package tasks - are our lifeblood at my company and this trend of random and serious crashing on large package files is very disturbing to say the least.
thanks,
Wil
I recently updated the datatype of a sproc parameter from bit to tinyint. When I executed the sproc with the updated parameters the sproc appeared to succeed and returned "1 row(s) affected" in the console. However, the update triggered by the sproc did not actually work.
The table column was a bit which only allows 0 or 1 and the sproc was passing a value of 2 so the table was rejecting this value. However, the sproc did not return an error and appeared to return success. So is there a way to configure the database or sproc to return an error message when this type of error occurs?
I am looking to test this feature - and the "Transaction Performance Collector" has recommended me a table to port to In-Memory OLTP.
I have now tried the "Table Memory Optimization Advisor" tool.
After a couple of tweaks to the table design - the tool is now passing validation but the tool is not allowing to progress to the next step:
Could it be down to not having enough memory? But would this not show in the advisor?

I've been researching AWE to determine if we should enable this for our environment.
Currently we have a quad core box with 4 gb of RAM (VMware). OS: Windows 2003 std, SQL Server 2005 std. 3GB is not set but will be as soon as we can perform maintenance on the server.
I have read mixed feedback on AWE, either it works great or grinds you to a hault. I would assume that the grinding to a hault is due to not setting the min/max values correctly or not enabling the lock page in memory setting.
We only have one instance of SQL on the server and this box won't be used for anything else aside from hosting SQL services. We do plan on running SSRS off of this server as well.
1. Will running SSRS and enabling AWE cause me problems? Will I have to reduce the max setting by the SSRS memory usage or will it share and play nice?
2. How do I go about setting the Max value? Should it be less than the physical RAM in the box? Right now its set to the default of 214748364, even if I don't enable AWE should this default value be changed?
3. It seems that even at idle the SQL server holds a lot of memory and the page file grows. If I restart the process in the morning, memory usage in taskmon is at 600mb or so. By the end of the day, its up around 2gb. How can I track down whats causing this, should this even concern me?
4. The lock Page in memory setting worries me. Everything I've read on this seems to give a warning about serious OS and other program support degradation. In some cases to the point where they have to restore the settings on the server before they can bring it back up. What are your thoughts on this.
I have a parent package that calls child packages inside a For Each container. When I debug/run the parent package (from VS), I get the following error message: Warning: The Execution method succeeded, but the number of errors raised (3) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
It appears to be failing while executing the child package. However, the logs (via the "progress" tab) for both the parent package and the child package show no errors other than the one listed above (and that shows in the parent package log). The child package appears to validate completely without error (all components are green and no error messages in the log). I turned on SSIS logging to a text file and see nothing in there either.
If I bump up the MaximumErrorCount in the parent package and in the Execute Package Task that calls the child package to 4 (to go one above the error count indicated in the message above), the whole thing executes sucessfully. I don't want to leave the Max Error Count set like this. Is there something I am missing? For example are there errors that do not get logged by default? I get some warnings, do a certain number of warnings equal an error?
Thanks,
Lee

Hello, I understand that we should use SSMS -> Server Properties -> Memory to put a cap on the SQL server memory usage, therefore it gives some space memory for OS, this is based on the fact if the max memory is not specified, SQL will use whatever available memory and eventually crash the system.
My question is that when a server has SSIS and SSAS services installed along with the SQL service. Would the max memory setting covers the SSIS and SSAS memory usage, or the SSIS and SSAS has to shared the memory with OS?
Thanks,
fshguo.
I am running Visual Studio 2005. I have an SSIS Package which is consuming a huge amount of memory. During the execution of the package the memory keeps increasing. Until finally i get an Out of Memory exception. I have run this package using dtexec, and in the BIDS. No difference. I do have some script components and have added some code to get the assemblies in the current appdomain. I do see that one particular assembly is increasing on every loop. VBAssembly every time it hits the script component is increasing by 6, and along with it the memory is climbing. What is this VBAssembly being used for is there an update to SQL Server Integration Services that I need?
Thanks! Aaron B.
sql server 2000 is running on windows server 2003 ... 4gb of memory on server .... 2003 was allocated 2.3gb nd sql server was allocated (and using all of it) 1.6gb for total of approx 4gb based on idera monitor software ... all memory allocated betweeen the OS and sql server .... then 4 more gb of memory added for total now of 8g ... now idera monitor shows 1.7gb for OS and 1.0 gb for sql server ..... 'system' info shows 8gb memory with PAE ... so I assume that the full 8gb can now be addressed .... why are less resources being used now with more total memory .... especially sql server ..... i thought about specifying a minimum memmry for sql server but i amnot convinced that would even work since it seems that this 1gb limit is artificial .... it it used 1.6 gb before why would it not use at least that much now ??
thank you
