Hello

I haven’t paid attention to our Zammad test system for a while, but today I wanted to log in, but Zammad wasn’t working. After a reboot I was able to log in again but now we have the following problem

On the monitoring page within the web gui we have

scheduler may not run (last execution of CacheClearJob.perform_now 3 days ago) - please contact your system administrator

/var/log/production.log has hundreds of info messages like:

INFO – : ProcessScheduledJobs running…

  • No load on the system, enough memory and space on the filesystem.
  • All services looks ok: zammad zammad-web zammad-worker zammad-websocket apache2 and postgresql
  • I can login to GUI and create a ticket.
  • System reboot didn’t solve the problem
  • There is also a process background-worker.rb which do something (checked via strace)
  • Any other process which I should check?
  • Currenty we have on test system no e-mail configuration, can this cause the problem?

where can I go on with investigations?

thanks for any hint :slight_smile:

After a long weekend, the problem solved itself. No clue why, we didn’t touch the system.

In the logs I see running jobs but all with “status is: sleep”

Last week we had some jobs with “status is: run” e.g.

  • ‘Execute import jobs.’
  • ‘Process ticket escalations.’

If someone can explain the problem, that would be fine, if not the ticket can be closed.
