We have been running SQL Server 7 for the past 6 months, with no problems at all. All of a sudden, we have received the error message 17050, that the maximum limit for connections has been reached. We cannot now start Enterprise Manager or do anything. We have tried fiddling with licencing in control panel but to no avail. Does anyone have any idea why this has suddenly happened? Any tips would be great!
Cheers.
I'll try and keep this brief so in a nutshell:I have large distributed java system running on a Windows 2003 server(4cpu 8Gb memory).Periodically the following exceptions occurs in the servers:java.net.SocketException: No buffer space available (maximumconnections reached?): recv failedI know for a fact we are not using too many TCPIP sockets or runningtoo many socket servers.I have googled this error and found very little to help me.What buffer space is this?What does recv failed mean?(Is it at all relevant that sql server is running on the same box?)Any advice appreciated.Thanks in advance.Dan
View 5 Replies View RelatedI am trying to setup transactional replication between Server A and Server B. There are 265 databases on each server.
I am running SQL Server 2005 on Windows Server 2003. The problem comes in at the 201st database. The message in the SQL Server Agent Error Log is :
Warning,[398] The job (WSSWPG09-EmpirePaint-WSSWPG06-104) has been queued because the maximum number of working threads (400) are already running. This job will be executed as soon as one of the working thread finishes execution.
SQL Server's max worker threads is set to 0. The Distribution, LogReader and T-SQL subsystems have been increased to 200 max_worker_threads.
Is there some other setting (maybe a Windows Registry setting) that can be configured to fix this? Or have I just hit a physical maximum of the processor?
Any help is much appreciated.

What error does an application get that tries to insert additional data via ODBC?
We have a big software that run a warehouse distribution center, written in .NET Backhand is a SQL Server 2008 R2 STD database.
Now, it seems there is a problem with the sessions not being properly closed after each call to the DB. Here is the message got form SQL:
DESCRIPTION:A new connection was rejected because the maximum number of connections on session ID 57 has been reached. Close an existing connection on this session and retry.
In the .NET code, connection is made with the following code:
If oConn Is Nothing Then oConn = New SqlConnection
If oConn.State = ConnectionState.Open Then oConn.Close()
With oConn
.ConnectionString = "Server=" & Server & ";Database=" & DB & ";User ID=" & User & ";Password=" & Pass & ";Connection Timeout=" & 5 & ";MultipleActiveResultSets=" & True
.Open()
End With
This code is called once, at the opening of the software
StoredProc are call with the code:
Try
oCmd = New SqlCommand
With oCmd
.Connection = oConn
.CommandType = CommandType.StoredProcedure
[Code] .....
So every Command is closed after execution, yet, they stay active in the SQL Server. Is there something I'm missing here?
Hello SQL gurus!I am trying to write a query that will return a set of continguous rowsfrom a table, and limit the number of rows returned when a maximumtotal has been reached by adding a value in one of the columns.For example, the two columns below represent 2 columns in a table.a 2b 2c 2d 3e 4f 5g 5I want to start at, say "c", and return all the rows after it as longas the sum of the numbers in column 2 (starting at "c") don't exceed10. The result I'm after would be thusc 2d 3e 4....because 2 + 3 + 4 = 9 < 10Any ideas? Many thanks.
View 4 Replies View RelatedOne of our production databases was setup mirroring, log shipping and replication on it, the log file was setup unrestricted growth. This morning one index rebuilding process generated lots of logs, and the log file disk ran out of space, the database was in recovery mode. so we had to disable log shipping, pause mirroring and replication, expand log file disk, restarted SQL instance to fix the issue. Now we want to setup the log file to maximum size 80G, the whole log file disk is 120G.
So if the log file reached 80G next time, we can change the max size to 90G or 100G and it's easier to fix the space issue. My question is, if the database log file reached max size,
1. is the database still available?
2. Will the active session causing the issue be rollback to release space back?

We have a production server that is configured to 100 user connections.
Without any reason, the maximum connections had been exceeded and users
can no longer access the sql. But if you sp_who , it displayed only
4 user connections. Since, I have an open connection before this error
happens, i was able to execute sp_who. This happened 4 times since we
installed the sql server. the version is 6.50.422 sp5a with hotfix.
To all gurus out there, can you give light into this problem?
Thanks in advance.
Hi All,
I have a Windows 2003 Server. Planning to use SQL Server to act as the main Database Server which needs to cater to over 100's of simultaneous connections.
Can anyone share with me the default maximum simultaneous connections and the maximum allowed simultaneous connections for the following versions:
- MSDE
- 2000
- 2005 Express
- 2005
Hope I can get more professional advice from you guys.
Thanks.
Newbie here.I've got my database set up in SQL 2000, and have started an Access adpfor a front end. I have 10 licenses, and at the moment the onlyaccesses are the server through Remote Desktop and one person into theADP. I started getting ODBC timeout errors when running a complexquery, so I started poking around. In the logs there's messages sayingthe maximum of 10 user connections has been reached, over and overagain. I'm not even certain that these problems are related, but itdoesn't look good.Why are all 10 connections used when there's only the server and oneclient? No one else has access to this server. And how can I stop theODBC timeout? That paticular complex query is the whole jsutificationfor using SQL over Access, so I kind of need it to work. :)Thanks in advance, maddman

Hi,
I have an application with a DAL that has an interface with SQL Server.
The application has 400 users that open the web forms.
My question is:
Is there a limit of the parallel connections that can be opened? Or the IIS is managing all the access to the DB? Should I worry about the performance Or it's normal behaviour for ASP.NET applications?
Thanks
If I deploy a database to the web using sql express 05 is there a limit to the number of connections that can be made on it? I have read posts stating that but cant find any documentation from MSFT that supports that idea. I just know that it has a limit of a db size to 4 gigs.
Thanks!
Hi,
I read that there's a "tecnical" limit of 32767 concurrent connections for SQL 2005 Express, and that SQL 2005 Express uses only 1GB of memory. So, what's the number of practical concurrent connections SQL 2005 Express can handle? Is it 200 ,300, 0r 400...? How much memory is consumed by every connection?
Thanks in Advance.
Hi,
Environment:
I have a Sqlserver 6.5 production server used for web based applications
Compaq 5500 4 GIG RAM, 4 processor
Sql Memory config on that server is 1048576 (which is 2048 MB)
and the run value is 640000 (which is 1250 MB).
runvalue for user connections was 500
We have only 90 user connections may increase upto 100 depends on the connections. We don't have any overload on that server.
Error: I was seeing
"unable to connect maximum no. of 500 configured user connections are already connected" in the error log.
Action Taken:
I increased the user connections to 600
and rebooted the server. Immediately the same error I can see in the error log. But we have only 20 user connections at that time. I can able to connect.
Please advise me to get rid of this error.
Thanks,
Anu.

1. PhoneID is nothing but the participant in the call. PhoneID = 1 is twice from above. Which means 2 particpants (Same call )with 2 numbers with their callstarttime and callendtime. Similarly for PhoneID =2, there are 4 participants. And the list goes on for a day and then for a month.
2. For example a phone call P1 with 2 participants is going on for a particular day. We should not consider the same phone call having 2 participants involved. So that the concurrency would be 2. We have to ignore that here.
3. Only to be considered is other Phone calls for that day. Lets say P1 having call with 2 participants, P2 having some 4 participants which fall in the time period of P1. Then we should consider P1 and P2 the common period
4. In order to find number of concurrent calls happened for a day basing on callstarttime and callendtime. What would be the query?
5. Should consider the Timeperiod or the bucket with 1 hour as the period.
6. A Phone Call P1, Phone Call P2, should have matching (common) time ( keeping all the scenarios) is required for this query.
Result for Concurrent calls for a day should be like below. Should get all the concurrent connections happened for a particular day.
Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
Jan-01-2015|01 to 02|3
Jan-01-2015|11 to 12|2
Jan-02-2015|04 to 05|5
Jan-02-2015|12 to 13|13
........
ii) So once the above is achieved.
Have to find the Maximum concurrent connections for day from the above.
For below Maximum Concurrent connections are '3'
Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
Jan-01-2015|01 to 02|3
Jan-01-2015|11 to 12|2
Hence the Result for Maximum Concurrent Connections would be
Date|TimePeriod/Bucket(hr part)|MaxConcurrentconnections|
Jan-01-2015|01 to 02|3
Jan-02-2015|12 to 13|13

Hi
I've implemented an SQL-CLR stored procedure which makes an HTTP connection using the WebClient class to a server where the processing on the web server takes 10 seconds.
If I fire off a bunch of requests to the stored procedure, e.g. 80 in 1 second I noticed that SQL Server 2005 (Express Edition) only allows 2 concurrent network connections at a time.
I can confirm this by looking at the timing of the results when they come back, basically I get 2 results every 10 seconds and by doing a 'netstat -a' on the web server I notice that there are never more than 2 HTTP connections from the SQL Server at a time.
Is this some sort of sheduling policy in terms of the number of concurrent external network accesses allowed by CLR objects running in SQL Server? Or some side effect of the way the WebClient class blocks in terms of waiting for a network response?
I was expecting all 80 of the requests to block waiting on a network response almost immediately and then for all 80 of them to pretty much complete and return 10-11 seconds later.
[Microsoft.SqlServer.Server.SqlProcedure]
public static int CreditAuthorisation(string Name, decimal Amount)
{
WebClient client = new WebClient();
string result = client.DownloadString("http://someserver/Test.aspx");
return int.Parse(result);
}
Cheers

I have some code I build 2 weeks ago which I’ve been running daily but it’s suddenly stopped working with the following error.
“The table "tbl_Intraday_Tmp" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit” When I google this there seems to be a related to tables with vast numbers of columns.
My table tbl_Intraday_tmp is relatively small. It has 7 columns. 1 of varchar(5), 3 of decimal(9,3) and 2 of decimal(18,0). The bit I’m puzzled with is it was working and stopped.
