We have a problem with a sporadic deadlock that occurs on our primary production Sharepoint 2007 farm. When it occurs we have to manually reset IIS as all sites stop responding. When it occurs it is usually around 5:00AM when the UK would be coming
on line and working
1 x WFE, 1 Search, 1 SQL server
Sharepoint 2007 SP2 with Dec cumulative updates
2 primary web apps
I have installed debugdiag and created a crash rule to capture any faults in IIS process, but that is not capturing the data when the deadlock occurs.
When I setup a hang rule it fails on the verification of URL with a 401 Unauthorized error. I have turned off loopback checking on our test server and it fails with this same error. I am able to access the site via IE on the server. This
hang rule is the only thing i see that would trigger a dump to be captured when the site did not respond.
Is there a better way to approach this? The goal is to have something configured to trigger a dump when the deadlock event occurs
