There is a 12 hour gap in my error logs where no information is reported and it occurs right before a server crashed. Is there another way to get information on what caused this crash... a reason why SQL Server stopped reporting information udirng this time?
It sounds like, possibly, the problem was 12 hours in the past and the crash just resolved it? How about errors in the OS error logs? There are only a few places to get errors from and it sounds like your error did something to the log. That or someone edited the log during/after the crash (the log is just a text file).
