Does anyone have any experience with this error:

01/04/2006 05:33:29  ANR7838S Server operation terminated.
01/04/2006 05:33:29  ANR7837S Internal error LOGREAD566 detected.

Our TSM server crashed (running on aix) and we had to restore to
yesterday.  Trying to find a cause so we can prevent it from happening
again.

I see info in the knowledge base about extending the log, but the server
crashed and we didn't have that opportunity.

thanks
