imp/horde trouble

[Gabriel E. Gaitán]

Hello,
I have horde 1.2.2 and imp 2.2.2, whit mysql 3.22.32, running in Redhat
Linux.
Sometimes, these packages present the following error when I´m checking my
mail:
Database error: Invalid SQL: DELETE FROM active_sessions WHERE changed <
'20010905143334' AND name = 'HordeSession'
MySQL Error: 1030 (Got error 134 from table handler)
Session halted.
How can I fix it?
Thanks for you comments.

gabriel.
