Do you mean that you migrated from Filestorage to RelStorage, backed by
MySQL, or do you mean that you re-wrote your application to use MySQL
directly (maybe via Products.ZMySQLDA)?

"Crashing" seems to imply that your Zope server is stopping:  the
indivdual sites you serve from that serve can't "crash", per se.  Or do
you mean that they are displaying error pages?

If the Zope server process is actually stopping, there may be something
in the error log which helps diagnose the problem.

If there is nothing in the error log, then it seems likely that your
server is segfaulting (maybe due to a bug in the MySQL library, or else
it is built improperly).  In that case, you might learn something by
running the server in the foreground (e.g, 'bin/zopectl fg', instead of
'bin/zopectl start'), or with coredumps enabled.
