We originally were running zammad 6.3, but one day, after we had a busy day with a lot of tickets ~200, the activity steam and over views stopped updating as detailed.
Figured something was broken, was slightly out of date, running a older debian, database was old, so reinstalled everything, and did a backup and restore on the newer zammad version, latest ubuntu and everything, and moved it to faster hardware.
This fixed it and everything was working just fine, but now, as more tickets come in, around the busiest part of the day, it breaks again, and stops working, by the end of the day it starts working again.
Im thinking there is some limit set somewhere that we need to increase in a config, probably for the websockets? But looked around and could not find anything anywhere, and logs do not show any errors or warns.
