Database log unavailable I am using SQL Server 2005 and I see the following message in event log (event id 9001)

"The log for database xxxx is not available."

After doing some research I found that it could be a corrupted database or possibly I/O related problem.
I tried running DBCC CHECKDB and it did not report any problem. At the end it shows following message:

"CHECKDB found 0 allocation errors and 0 consistency errors"

I just want to know if there could be any damage to the database or log and what other steps I have to perform to verify it?
Things to check:


Is your Log file size set to a limit?
Have you run out of disk space on the drive where the log file resides (seems unlikely)?
Is this a physical or virtual server?
What service pack are you running?
What, if any, are the preceding errors in the error log?
