Since a recent reboot of the K2000 appliance our PXE environment broke down, with the following error after booting machines through PXE:

Malformed response received from server. Please check configurations.

Logs keep telling me:

Attempting to open the table through MySQL Workbench results in the same error, 1194 table has crashed and needs to be fixed.

Last time I had issues with a database it was with the K1000 DB growing too large and the support sent me a patch for this, however regarding this error and the K2000 there seems to be no information at all.
I asume the "report" account has no permissions to execute repair commands within the database, tho I have not attempted this yet before I get a clear sign it won't mess things up.

Worst case scenario I'll have to install a completely new K2000 as asuming a complete backup of the current one will also bring me the corrupted database?

Is there any known fix to this? Perhaps an elevated DB account to execute repair commands? A patch to fix DB corruption? Or will perhaps uppdating the box to the latest SP1 version fix this by some miracle? (trying to upgrade the box while the database is corrupted is slightly scary)
