Zammad is not fetching imap email


  • Used Zammad version: 4.1.x
  • Used Zammad installation type: docker-compose
  • Operating system: Ubuntu
  • Browser + version: Chrome

Expected behavior:

To fetch e-mails

Actual behavior:

Does not fetch e-mails

Steps to reproduce the behavior:

Zammad fetches e-mails for a day or two after restarting the docker stack and then it stops fetching them. Restarting the docker stack fixes it for a while and then it stops again. I see the following error in Current Status:

channel is active but not fetched for 2 days
scheduler may not run (last execution of Chat.cleanup 2 days over) - please contact your system administrator
Failed to run background job #1 ‘SearchIndexAssociationsJob’ 1 time(s) with 3 attempt(s).

The scheduler container has the following error:

E, [2021-12-13T22:41:25.654868 #1-47157212163440] ERROR – : Retrying SearchIndexAssociationsJob in #<Proc:0x000055c748590870@/opt/zammad/app/jobs/search_index_job.rb:6 (lambda)> seconds, due to a StandardError. The original exception was nil.

I would appreciate some assistance.


Looks like your scheduler is dying unexpected.
The log lines you provided to not belong to a dying scheduler but searchindexing failing for whatever reason.

Without proper log lines we won’t be able to help you.
