Failed to run background job #1 'Observer::UserDeviceLogJob


  • Used Zammad version: 2.4.x
  • Used Zammad installation source: centos7 package
  • Operating system: CentOS 7.4
  • Browser + version: latest Chrome

Expected behavior:

  • System > Monitoring should be green :slight_smile:

Actual behavior:

System > Monitoring shows:

  • Failed to run background job #1 ‘Observer::UserDeviceLogJob’ 1 time(s) with 20 attempt(s).

Steps to reproduce the behavior:

  • Not sure. The only changes to the system were update to 2.4 as well as changing the way LDAP syncs our users. Users w/o groups assigned LDAP groups was set to Assign signup roles. Initially we had Dont sync.

Anyone an idea how to troubleshoot this issue? restarting Zammad didn’t solve it. Havent found anything valuable in production.log.
Thanks for your ideas.

Hello all,
the amount of failed jobs is slowly increasing. When writing the initial post, we had 20 failed attempts.
As of today its 22 attempts. The exact error message is:

Failed to run background job #1 ‘Observer::UserDeviceLogJob’ 1 time(s) with 22 attempt(s).

Anyone an idea what this might be? Or a hint how and where to troubleshoot?
Thanks in advance
