ORA-06576: not a valid function or procedure name

Hi DBAs,


DB = 10.2.0.4
OS = LNX AS 4

I'm getting this err from last 2 days.

ORA-12012: error on auto execute of job 188726
ORA-06576: not a valid function or procedure name

I dont see any failure jobs and invalid objects in my database. Can somebody helpme out to get out of this?

In trace file..
