A fatal error caused EMERGENCY SHUTDOWN

Hi all,

we work with maxdb V. 7.6.00.34. A job deleting records from a table causes the following messages in knldiag.err:

And this is the SQL-Statement:

Delete from SERVER_HIT where VISIT_ID in (select VISIT_ID from VISIT where FROM_DATE < subdate(timestamp,60)

May be there are indices on this table out of order.
If anyone can help, please don't hesitate.

Thanks in advance
