ORA-27466 when trying to stop scheduler jobs

Hello,
When trying to stop a schedule job, the job doesn't stop we get the following error:

ORA-27466: internal scheduler error: 1870
ORA-06512:  "SYS.DBMS_ISCHED", line 199
ORA-06512: "SYS.DBMS_SCHEDULER", line 557
ORA-06512: in line 2

Already tried the stop force and the error is the same.

I cannot find any information regarding this ORA-27466 in metalink, can anyone help out?

Thank you.
