Please see below for the answers to your questions. I hope this helps
to diagnose the problem. Please let me know if you need any more
information as this seems to be happening to more and more people.
Thanks.

Also, a note about the above query: that query probably caused the
crash or had something to do with it, but I don't think that is the root
problem. I believe that an INSERT is causing the problem and since the
INSERT causes corruption, the SELECT doesn't work right. Sometimes the
server crashes and sometimes it doesn't.

The check says "ok" now, but the table was corrupted after the crash. I
repaired it, but no messages were printed to the log. Usually a row is
lost however and sometimes a message like this is found in the log:
Note: Found 804 of 805 rows when repairing
