Hi,

I have the following error in the db2diag.log when I backup a DB2 database with TSM :

Starting a full database backup.

The backup command is successfull but the DB2 processus db2sysc 21195 writes a dump file ( t21195.000 bigger than 45 Go ) and monopolizes 98.8 % of the CPU...

Thanks in advance

Technical environment :

DB2 UDV 7.2 Fixpak 10
TSM ( 5.2 )
Linux Red Hat AS ( 2.1 )
