Too many open files


I am running Icinga on Centos 8.2.2004, i’m seeing an issue where icinga is crashing each day and in icinga2.log it only says: critical/ApiListener: Cannot accept new connection: Too many open files

Does anyone know how to resolve this?


Do you have pending signing requests on the master?
If I understand this open bug at github correctly this can be a problem:

Hello and welcome to the community @qvindesland!

Did you make any progress with this?

I would love to hear back from you and whether the issue linked by log1c applied to you (if you’re running Icinga 2.10 that would probably be it)

Have a nice day,
