Question : SQL Server 2005 - Time-Out Errors / Connection Failure

Hello,

We are running SQL Server 2005 Standard x64 Edition on Windows Server 2003 Standard x64 Edition. The server has 8GB of dedicated memory. The database size in SQL Server is 30GB.

We've a client program which remotely connects to SQL Server database. We've more than 7 locations. From past few days, we are keep getting "Time-Out Expired" following "Connection Failure" error messages.

When this error occurred, we restarted the MSSQLSERVER service and everything started working fine until next day. There is no error details available in Event Viewer (both in Windows and SQL Server 2005.) All software is up to date. The error occurred randomly on every day.

We asked our client application provider for support. They suggested us to run full index and set "remote query time-out" to 0 (unlimited). We changed settings according to their suggestions and restarted the server.

It works for couple of days and again displaying the same kind of error messages. We didn't changed any settings in the server from past months expect the recent changes for troubleshooting purpose.

There is no program running in background when this error is displayed. This is our system configuration:

Windows Server 2003 R2 Standard x64 Edition
SQL Server 2005 Standard x64 Edition
Total Physical Memory: 8GB
Current Physical Memory Usage: 5GB

Database Info:
Total Size: 30GB

I'm not sure where the problem is resides, but I suspect the problem is with the database or client application!

Any further help would be greatly appreciated. Thank you.

If you are not prepared to solve the problem by optimizing the query, then certainly re-indexing and/or rebooting the server every night may be temporary fix.  Eventually even that kludge will not solve the problem and you will have to roll-up your sleaves.

Sorry to be the harbinger of bad news.
