I need to permanently delete a re-generating job, but I can't find its source

I have used dbms_job.remove to remove all jobs from dba_jobs, but something is re-submitting a series of jobs every few minutes.  I have disabled all triggers and all external cron jobs have been stopped...  but more jobs keep getting submitted.  I have a single transaction record in v$transaction which is dated July and is very similar to the date/time of the re-generating job.  I would like to delete this transaction, but I don't know how.  I am hoping that the overall result of eliminating the job will also delete the transaction.  Can anyone please help me track down the source of this resubmitting job
