Oracle Enterprise Manager Jobs Failing Initialization The Enterprise Manager jobs on our RAC system recently started intermittently failing initialization with the following error:


  Error evaluating parameter sources/security checks/locks ORA-06508:
  PL/SQL: could not find program unit being called


We have tried bouncing DBConsole, re-submitting the job from the library and even recompiling the package being referenced.  This is happening to multiple jobs with about one execution in every ten scheduled succeeding.  Any ideas on what can be tried or checked?

Update: I've opened a SR with Oracle.
Oracle support has been no help.  After about a week of the jobs sometimes running they stopped running completely.  Every single job got an initialization error every time it ran and every time it was retried.  We are in the process of re-creating the repository and migrating to dbms_scheduler jobs.
