The handler for the table doesn't support repair

[Mean]

When i attempt to repair all of my database in MySQL, only

forumistannet.vb_session

Has got an error like The handler for the table doesn't support repair.

And sometimes my site shows database error.

How can i fix this and this is why gives error ??

That is normal for the cpsession and the session tables as they are HEAP (in memory) tables. Tehy can not be repaired but get rebuild at each start of MySQL.
