Facebook Twitter LinkedIn YouTube GitHub How to Troubleshoot SQL Server Connection Timeouts May 27, 2015Brent Ozar19 comments If your application can sometimes connect to SQL Server - and sometimes not - it can be really tough to troubleshoot. If SQL Server doesn't even hear the call, it can't log any sqlserver timeout errors. Here's the questions I ask to get to the root cause: When it happens, does sql server timeout expired the timeout period elapsed it happen to all applications? For example, do you have monitoring tools pointed at the SQL Server, and are they able to consistently connect

to SQL Server even when the problem is happening? Does it happen to all application servers? If you have several app or web servers, are they all affected? (If you've only got one, now is an excellent time to set https://support.microsoft.com/en-us/kb/2879704 up another one for troubleshooting, and balance the load between them.) Are all queries in the application affected, or just some queries? Sometimes I see long-running queries keep right on going, but only new connections are affected. Sometimes, your SQL Server just goes on vacation. Are there any errors logged in the SQL Server or application servers? In one case, we saw that all of the application servers lost network connectivity at the same time, on a regular basis. Turns out https://www.brentozar.com/archive/2015/05/how-to-troubleshoot-sql-server-connection-timeouts/ there was a bad switch involved. Is there a pattern to the days/times of the timeouts? Start writing them down or documenting when they happen. For example, in one case, we saw that the days/times were exactly correlated to the security team's regularly scheduled port scans. During the timeouts, is the app server able to ping the SQL Server? When all else failed with one troubleshooting triage, we put a free network monitoring tool on the app server to ping the SQL Server every 10 seconds. Sure enough, the next time the app had query timeouts, we were able to prove that even pings weren't working - thereby ruling out a SQL problem. Ask those questions, and sometimes you don't even have to troubleshoot SQL Server at all - the answers tell the whole story.

In this category the http://help.earthsoft.com/default.asp?W2205 error related to “Timeout” surely falls. If you are a web developer and receive the same there are a hundred sql server combinations why this can possibly happen. The web, results can sometimes lead us in completely opposite directions because we have not analyzed the root cause for this. I sincerely urge everyone when working with generic errors, look for specific symptoms and sql server database then use the trick of eliminating one after the other before a final solution can be arrived.This is one of the most common error which you would hear from web developers. Here is a typical error raised shown on the website. [SqlException (0x80131904): Timeout expired.

Tags: sql-server, troubleshooting Database - Troubleshooting - SQL Server - Timeouts Keywords: sqlserver, sql server, SQL Server, log file, log files The size of log files is related to SQL Server time-outs. With a large log file, if it is trying to grow by 10% (34584 MB) with the next transaction, a timeout error will occur. Please review the pointers below, in addition to contacting your Database Administrator to discuss which of these options is best for your situation. As a matter of policy, EarthSoft is not liable for any damages and/or data-loss that may occur as a result of changes to your database. Review the database recovery model and check which recovery model you are using by doing the following: Open SQL Server Management Studio Browse to your database Right-click and choose Properties Click on "Options" Note the Recovery Model (second from the top) As explained in the link above, if you are using the "Full" recovery model, then the log file will never shrink by itself (and will continue to grow). It may also be helpful to review the following: Managing the Transaction Log Troubleshooting the Transaction Log Shrinking the Transaction Log Talk with your DBA and determine whether you need to manually increase the size of the log (to avoid the time-out), or whether you want to shrink (truncate) the log. If you decide to shrink the log, the link to Shrinking the Transaction Log above explains the
