E-Mails (including notifications) get sent with a long delay
Steps to reproduce the behavior:
We had a internet outage over the weekend and one systems (KIX installation) sent failure notifications as hell
All the messages were immediately received and processed by our zammad instance
But now notification emails are dripping in one by one on a 2 minutes interval. (We have received about 300 failure messages…) Additionally all outgoing emails will not be sent at the moment and we assume this is due to pending notifications…
Hi, I have tried as many information as I could. It is very frustrating as the CPU is most of the time doing excatly nothing and still there is this “hard coded” two minutes delay with everything. Worst thing: every new mail (to be sent by agents / notification) will scheduled after the existing ones…
Honestly this issue drives me nuts and makes the whole system unusable…
This setting is only relevant to user sessions.
Setting this to 1 or 2 should be fairly enough for e.g. 15 users.
Using this setting will allow your scheduler main process to have more time for delayed jobs and other timed tasks.
It can be perfectly normal for a Zammad installation to have spiking numbers of delayed jobs, however, they should decrease in a timely manner. This sometimes isn’t exactly possible if e.g. thirdparty systems like mail servers are delaying sendouts etc.
