High load / cpu usage since a few days for script/websocket-server.rb


  • Used Zammad version: 4.0.0-20
  • Used Zammad installation type: docker-compose
  • Database: Postgresql & Elasticsearch comming with the docker container 4.0.0-20
  • Operating system: Ubuntu 18.04.6 LTS
  • Browser + version: Firefox 107

Expected behavior:

  • Moderate CPU usage

Actual behavior:

  • Since a few day htop shows me a very high load of script/websocket-server.rb -b -p 6042 start.

When I reboot the server, for a few minutes load is OK, but then the process is started again and shows a permanent high load.

Steps to reproduce the behavior:

  • Reboot server and see screenshot :wink:

Any ideas? Thanks!!!

Update to Zammad 5.3 to rule out any very old bug.

OK, thanks!

After some weeks of high CPU load, now - nothing has been changed - the load is normal again.
But I will update the system as soon as possible.
