System: vmWare-VM, 4 cores on one socket, 32 GB RAM full reserved, 16 GB swap
Expected behavior:
qucik response when interact with web-gui
Actual behavior:
system slow / becomes not usable
Steps to reproduce the behavior:
restart machine
After restart the machine on ruby-process from user zammad runs permanent at 100%, another ruby process ist created. Round about 4 hours later system becomes unresponsive.
Get’s slower over time definitely sounds like a database connection issue, because that’s basically the only thing that fills up over time in a relevant that is performance relevant. The config might be faulty and not apply the maximum connection setting correctly.
Additionally to that (because I’m lazy and performance tuning is a very broad and complex topic), this video might help you pinning down most of the issues on a normal level.
this video made my day. Now I’v understand the processes an dependencies from zammad. Now my system is stable and performant. Thank you for quick response an exellent help.
If you don’t know what to look for, it becomes difficult for people like me.
My main problem was the open changes and a ticket with 1200 notifications. Deleted – and the ruby process is using 1% CPU. Thanks to your help, I now know where to look. Thanks again!
