Looks like you found two bugs at once. The first one is that someone mysqld
segfaults, probably a bug in processing some query or possibly some OS issue,
but there is not much we can tell at this point - the only way to track it
down would be if you had full logging enabled and saved the last few queries
before the crash, and took a full snapshot of the database at the time of the
crash.
Second bug is that BDB could not recover after the crash - I hope you have
backed up the logs before you deleted them - we will need them to debug the
problem. If you still have them, upload them to
