Event InformationAccording to Microsoft:
A process is waiting to acquire a latch. This problem can be caused by an I/O operation taking too long to complete. Typically this type of error is the result of other tasks blocking system processes. In some instances, this error may be the result of hardware failure.
Try the following to prevent this error from occurring:
Reduce workload.
Check for associated I/O failures in error log or event log. I/O failures typically point to a disk malfunction.
Check the error log for non-yielding tasks and other critical errors.
If critical errors such as asserts frequently occur, resolve these problems.
