Dear Experts,
recently, we observed that the SQL Server was not responding,and so the application (SCOM 2007 R2) stoped working. Upon investigation, I found the following errors( may be aroung 100s) were logged in the SQL error log.
Timeout occurred while waiting for latch: class 'LOG_MANAGER', id 00000000051E09F8, type 4, Task 0x00000000CCAA9288 : 0, waittime 300, flags 0x1a, owning task 0x000000011554FB88. Continuing to wait.

I could not even open the event viewer or services console or the SQL Management studio at that time. All are crashing or not responding. So the only option left was a server reboot. even a remote reboot did not help. I have to force shutdown the server at the Datacenter. After that, all things became normal. After that, as I checked the SQL error logs, I found these errors during that time range. There is no other error in the application or system log of the system. So I am suspecting that, this SQL server error was the culprit, so need to understand what these error are, why they occur and how to get rid of it.
Thanks,
Thanks
