Sql Server failed during the middle of the night.  I had to reboot the whole server to get it back up and running.  I have a bunch of errors around the time of the failure.  Attached is the error that seems most relevant to my problem.   Can some one look at the screenshot and tell me what is the problem and what is best course of remediation.
