Any idea what the users were doing when it crashed? Was it just opening
the mailbox or opening some mail or deleting/copying mails?

Some kind of a way to reproduce this would be helpful. Or I guess in
your case even a backtrace, since all the previous ones have been with
COPY command and mbox.

BTW. these can be "no" if you're storing indexes locally.
