As it turns out: not all the time, and completely random.

I've seen some time in the past on a SCO system that a job was started
twice. This seemed to be a combination of time synchronisation and bad
programming. It was random and didn't happen all the time. Sounds very
similar to your problem.

The error is indicating that one job is started when the previous job
hasn't finished yet. The "0 seconds" indicates that the jobs are started
simultaniously.

Try to find (perhaps: enable) the log for cron so that you can see which
job is started and when. I still think that it is cron related.

If not then I'm out of ideas and cannot help you.

Regards,
Alex
