SOLVED Kanboard getting not responding

[Camille]

Hi,
Since a few days, our Kanboard instance ends up stopping responding a few hours after a reboot.
We have a few errors like

[mpm_prefork:error] [pid 1] AH00161: server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting

in the logs. Could that be related ?

Thanks,
Camille

@Camille Have you tried increasing the memory limit? https://cloudron.io/documentation/apps/#increasing-the-memory-limit-of-an-app

[Camille]

Hi @girish Yes I did. It's about 15 Go, and plenty of it is free, so I'd be surprised it was the problem.
We have 15 concurrent apache processes and that's the value in the mpm_prefork.conf file, but as it's read only, we cant' change this value ; and also, because those processes accumulate, increasing the max value would just postpone the problem, I'm afraid.

Apparently, it was related to email notifications.
