I've got a SharePoint 2010 environment. For some unknown reason the SharePoint Timer service keeps crashing. My Event viewer shows the following event:

I've already spent hours searching online for a solution, but to no avail. Any help is welcome.

  • Can you check the ULS logs and see whats happening there ? – ArkoD Aug 7 '12 at 12:44
  • It can be helpful to find out what was changed in time before the first crash. – IAfanasov Aug 7 '12 at 12:46
  • @MossFarmer - The frustrating thing is that there are nog relevant entries recorded in the ULS Logs. The Report ID does not turn up when i search for it. Is it possible for me to fine tune the logging to catch more ? – TempaC Aug 7 '12 at 13:17
  • @IAfanasov - This is a new SharePoint 2010 installation. The day these events started showing up I configured SharePoint Server Search, installed SharePoint Designer 2010 and added a Warmup solution. The Warmup solution i'm using might be the culprit since it runs every 15 minutes (queue dramatic music). I've set the runtime of the warmup script to 30 minutes to see if the owstimer.exe will crash every 30 minutes. – TempaC Aug 7 '12 at 13:26
  • You can enable diagnostic logging through SharePoint Central Administration and check once again. Its highly improbable that a timer service crash wont be logged in ULS. – ArkoD Aug 7 '12 at 13:39

The solution in this situation: Check the custom timer jobs.


Thanks for this. I had this problem where the SharePoint Timer Service was crashing every 20 mins, and then all SharePoint timer jobs would crash. To work around this i had to kill the PID ID for the sptimerv4 service.

When I first installed SHarepoint 2010 Standard, i found that a warmup was required. I downloaded a Sharepoint specific one and this is what has been causing the problem. I have now disabled it and everything running fine. Took me ages to get here.
