I 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 ?

Is there any setting in IS that I should have adjusted in order to avoid this message?

View 12 Replies View RelatedI 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.

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?

The merge process could not allocate memory for an operation; your system may be running low on virtual memory. Restart the Merge Agent.
hi,
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

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 hitting a crippling 701 "insufficient System Memory" error intermittently in out production environment. I haven’t gotten anywhere with PSS in two weeks. The error has occurred 4 times over the past two weeks, crippling our SQL server and application each time. When the error occurs it lasts for 5 to 20 minutes, causing the app to time out, refusing new connections, and a massive slow-down of anything that is running. SQL has recovered on its own two of these times. It recovered following a Kill of hundreds of threads reporting “SEMAPHORE WAIT�. The most recent occurrence nailed all 16 processors at 100%. We were forced to issue shutdown with nowait. I have been monitoring Perfmon very closely; there are no symptoms that precede the error. Each occurrence captures a different query. Any of the queries, when run from Management Studio, complete in under a second. DBCC MEMORY STATUS reports all memory as being in an unstressed state. The first time the error occurred there were 10 GB still available on the server.
Has anyone else experienced this problem or anything similar? We don’t use linked servers or table valued functions (there are known memory bugs related to each of these items)
The following server and configuration has been running in production for 6 weeks with no issues:
.SQL 2005 EE SP1 Post SP1 Hotfix kb918222
.Win 2003 SP1 (dedicated box)
.Quad Dual Core 3GHz
.32 GB memory
.AWE enabled
.No memory related flags in boot.ini
."Lock Pages in memory" set for SQL Startup account
.1 Instance (default)
.1,994 OLTP databases avg less than 100MB each
.1,200 active user threads on average (from connection pool of avg 4,000 concurent users)
Any comments would be appraciated
Just wondering if anyone else has seen any memory issues with cross instance communication. Just this last week we moved from single instance to cross instance communication. I started up a process that will move 3,000,000 messages through service broker, but after a couple of hours the server tanks out and we get insufficient system memory errors in the sql error log. If no one else has seen or experienced this then I'll probably get a ticket opened to see what it may be. It's just that the change in our service broker network was the only change I was aware of on this instance.

Hi,
I have started experiencing the following errors
"Unable to allocate memory for a hash node heap"
"The system reports 99 percent memory load. There are 8584744960 bytes of physical memory
with 5799936 bytes free. There are 8796092891136 bytes of virtual memory with 8794956038144 bytes free.
The paging file has 7447801856 bytes with 5201920 bytes free."
The packages running have been running for the last year with no issues. Admintidley they were the only jobs running against the Instance.
I have now introduced additional databases and packages.
The package do not over lap when they run so there is currently no contention for resource.
I have no idea where to start looking to identify the culprit.
I have observed the available pagefile being completely consumed and physical memory. The only way I can get it released si by bouncing the instance.
the only thing that has changed is pagefile. The system has 8GB RAM and was configured with a 4GB pagefile. I have recently created a second pagefile on
an alternative disk of 12GB and reduced the 4GB pagefile to 100MB and left it on the root drive. When I view the pagefile size in properties, it says that there
is only 100MB even though it creates a 12GB pagefile.
Can anyone shed some light on my problem?
I appreciate your help

Marcus
We're experiencing the following problem on our servers:
Server: Msg 701, Level 17, State 1, Line 3
There is insufficient system memory to run this query.
I've been able to fix the problem by a)Lowering the Max Server Memory and b)Minimum Query Memory.
However, Microsoft state there is a hot fix available for this issue at in KB Article 817262 (
http://support.microsoft.com/default.aspx?scid=kb;en-us;817262&Product=sql2k).
Any idea how one is supposed to contact Microsoft to get this fix without paying?

Hello,
We receive this error after running a complex query. Could someone please shed some light on what this means exactly?
One of our developer said we needed to purchase a server with more memory, but would SQL Server not simply just run slower by using virtual memory instead of physical RAM?
I know there is a limit and servers must be upgraded as the processing requirements increase, due to data set size increases for example, but we have just been told to "purchase more power because after a while as you process more rows, SQL Server will require more resources"
Any comments on this would be really appreciated.
Is there an possibility to assign confined system memory to mssql2005 ? Because some other programes needs system memory too.
View 2 Replies View RelatedI'm looking for a sanity check. Service broker and Event Notifications are new to me, so it is possible I'm either abusing or incorrectly using the technology. I'm experimenting with using Event Notifications and Server Broker to log error messages. The process works pretty well as long as I don't do something stupid such as stressing the process by calling raiserror in a loop of a 100000 - twice. It processed for a while, but eventual either SQL Server terminates (sev 25) or I had to force the SQL service to stop by killing it's process via task manager. I could not connect to SQL Server or stop the service normally.
I have several general questions. I think they are good questions. Any thoughts or suggestions would be appreciated.
1) I'm looking into generating deadlock and blocking email alerts. It appears that Event Notification is the way to go since there are very few events and I can respond to the event with an email. Is there a better method to automate blocking and deadlock email alerts that include event details?
2) If I wanted to retain some history of errors for the developers, should Event Notifications be avoided if a high number of errors can be generated by a badly formed T-SQL? Avoid TRC_ERRORS_AND_WARNINGS and USER_ERROR_MESSAGE? (I could tell the developers not to be stupid, but why would that stop them if it does not stop me?)
3) Is there a way to efficiently filter a Event Notification from entering the queue before the Receive statement is called? I get some events that I throw away after receiving them. For example, perhaps I want all events from all non-system databases without having to add a notification for each single non-system database. Or I want all errors with severity 11-17 only?
4) Is there a trick to filter out events from the procedure activated by the event. I tried using raiserror to debug a procedure without thinking. The result was that the queue never was empty because the processing produced more events to process. As a result, I don't use raiserror and use a try-catch to avoid raising errors in the procedure activated.
5) I can receive one message at a time using local variables or receive a batch of messages using a local table. Is a small batch the best way even if there is memory pressure?
6) In the activated procedure I continue processing in a loop until there are no more messages. This seems to be the most efficient. Is this always the case? Should I exit the procedure after a set number (large) of messages have been received? The procedure would activate again to continue processing?
7) Is there any point to using the MAX_QUEUE_READERS setting when processing event notifications? Should it be 1?
8) I currently get the next conversation group id and process its messages within a transaction. Is this a bad idea with event notifications? Should I just call Receive and get the next batch? I don't really care if I lose some messages if things are going badly. Should I avoid wrapping the receive in a transaction?
9) I could run a trace that starts with SQL Server; however, I think my only choice is to log to a file. Is there a way to trace to a table using SQLTrace without running profiler? I would like to automate the process and have the data in a table so that it can be easily queried and parsed for each database/team.
10) Is there a way to fix my process and handle 100000 messages a minute? Is there a way to skip messages when it gets to busy? Can the query generating the messages get throttled - perhaps along with the query designer - before the server gets into trouble? Query the memory used by a queue and drop/create the queue with a delay if there is an issue?
I'm using a single CPU test machine with only 1 GB and 2 GB pagefile and a single disk. OS: Windows 2003 R2 SP2. SQL: 9.0.3054 and on 9.0.3228 (update package 6 just came out today). I could add memory, but I think that would just permit me to queue more message before running into trouble.
I'll add code shortly - length limit.

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 Windows sever 2012 with sql server 2012 enterprise. Ram size is 22GB. Sometimes SQL sever takes 95% memory.My question, How to reduce memory size without killing any process because it's production server.So there are many background process is running. And,Is there any guides to learn why Memory is raise d so high and how to reduce it.
View 10 Replies View RelatedHello, 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.
