Failed background jobs, performance and search degradation


  • Used Zammad version: 4.1.0
  • Used Zammad installation type: Package
  • Operating system: Ubuntu 18.04.5
  • Browser + version: Chrome 92

Expected behavior:

  • Searches return results, generally responsive UI.

Actual behavior:

  • Searches do not return results, or take a long time to load. Delays of a few seconds when selecting and updating tickets.

Steps to reproduce the behavior:

  • Reboot server, allow to run. Within a few days, performance degrades and searches stop working.

In the monitoring tab we also get errors along the lines of:

  • Channel: Email::Account in Can’t use Channel::Driver::Imap:#<EOFError: end of file reached>
  • 442 failing background jobs
  • Failed to run background job #1 ‘SearchIndexAssociationsJob’ 7 time(s) with 125 attempt(s).
  • Failed to run background job #2 ‘SearchIndexJob’ 3 time(s) with 55 attempt(s).

Is this something up with elasticsearch? Any help would be appreciated.

This looks to degrade and inhibit the use of Zammad significantly.
