Hi,
I've started migrating my sites to mariadb which is supposed to be a
drop-in replacement of mysql. Both run on the same C6 box. DB folders were
moved to a new location after both DB servers were stopped and properly
upgraded. There were no reboots or power failures. Nevertheless I see these
error messages in the logs:

Note that after the crashed table was repaired mariadb reported multiple
crashed tables in the same DB after restart. Any pointers? Never had such
problems with mysqld. Is mariadb reliable and stable at all?
