Scheduled job eats up temp dbspace

Hello, Just upgraded my customers IDS from 11.50.FC5 to 11.70.FC5. When the scheduler starts it kicks of one job per database (38 databases). The name of the jobs are "autoreg migrate <db-name>" These jobs seems to fill the temp-dbspace which is 40 Gb big. The only way to stop the instance from crashing is to shutdown the scheduler. I deleted all these jobs from Open Admin Tools but when i start the scheduler the comes back ? What are these jobs for and how do i get rid of them ? Anyone who know ? /Plexor
