We recently upgraded from MySQL 5.x to Percona Server 5.5
The system is RHEL 5.3 x64 under Virtuozzo. The VE has no limits on hardware (it is the only VE running on host) and has 34 GB of RAM.
The ‘upgrade’ was done via setting up new server (virtual machine, actually), and then transferring innoDB files via Xtrabackup and opying the appropriate .frm files/folders. It went flawlessly.
However, I have experienced the following issue today while trying to drop a test DB (non-empty):
Page directory corruption: infimum not pointed to
followed by crash dump and restart of the server.
This occurs no matter if dropping an old (migrated) database or new one, as long as it is not empty.
Dropping a table from the DB produces the same result.
creating, inserting, altering…everything else works as far as I have observed.
Please help (or at least point me in the right direction)!
