[2.5.x] Quartz jobs randomly stop running.

[Nathan Keiter]

I have two OSGI plugins which schedule quarts jobs in production environments.  They each schedule a job that runs once daily (at different times.)  The jobs will run on schedule for weeks or months at a time, then suddenly stop running with no error.  If I look in the "Job Scheduler" admin page under the "System Jobs" tab I see the next run date is in the past.  There is no consistency with this and it only happens one job at a time, (not globally to both jobs on the same server.)  It's just quite random which one will stop running and when.

Currently the remedy is to stop/start the OSGI bundle to reschedule the jobs.  This works but is not ideal.  Does anyone have any idea why this would happen?  Any suggestions would be appreciated.

Job 1 runs 0 30 3 1/1 * ? *

Job 2 runs 0 35 3 1/1 * ? *

Thanks,

Nathan

Same problem with me?Does any one know solution or have some idea how to find root cause of it.

dotCMS Quartz jobs are highly unreliable. We gave up on using them long ago.

 

Use cronjobs or windows scheduler instead.

 

Have a shell script on the server hit a servlet to trigger your process.

 

You can IP restrict the servlet to avoid having unauthorized executions.

Well OSGI ones anyway.  You might have more success with a static plugin, but what’s the point in that…
