cron problem

RJA — Fri, 08 Jun 2007 10:18:44 GMT

Having a problem with cron. This is the error:MAXRUN (25) procs reached Fri Jun 8 10:13:00 2007
Jobs that were issued by cron never seem to complete, get run again by cron and eventually we get the same error message again. If we kill off some of the earlier scheduled jobs, cron takes off again but the jobs don't complete again. Any ideas?

Hi,

As the error message says, only 25 processes (MAXRUN), can run from the cron at the same time.

You can increase this number by modifying the max_jobs parameter in /var/adm/cron/queuedefs

However you should probably only do this as a workaround until you determine why the cron jobs are hanging... Are they doing anything out of the ordinary ?

Hope this helps,

Regards,

Rob

What happens if you run the job manually? It hangs too or completes?

Can you redirect stdin and stdout to some log file for the job runned by cron so you can know where it stopped?
