[RESOLVED] Generic Agent randomly does not run jobs

[yackleym]

Hi All,

I recently noticed that my OTRS 3.0.11 system is having issues when running scheduled jobs. I have a batch of jobs that are supposed to run every ten minutes, but now it seems that it randomly does not run all of the scheduled jobs. Checking /var/log/messages, it does not show any errors, just that it sometimes does not run the full list of jobs.

Here is an example of searching for entries pertaining to one job that should run every 10 minutes, you can see that it does not and the times that are missed do tend to vary. Any suggestions on where to start looking? Thanks!

EDIT: It is not just this one job, it sometimes runs more of the jobs than other times. Sometimes it runs all the jobs, other times it runs half or a third, etc.

It appears that we were being hit by a known bug, "Skipped GenericAgent.pl cron executions" http://bugs.otrs.org/show_bug.cgi?id=5782

I manually patched the otrs.GenericAgent.pl and that appears to have resolved our issue for now, while we wait for a maint window to bring the system up to date.
