Hi

Succesfully migrated from 6.07 to 7.0.0 last week. Did a database check prior to migration and all was fine.

However, I received this message at 11PM last night.

Database errors found.

To my knowledge, no disk errors happened on the server.

What could be the possible causes ?

The REPAIR TABLE option mentioned here is a zimbra function ? how do I activate this command line and make sure it doesn't happen again ?

Thanks.
