That’s described in the linked issue in the `Verify` section.

```auto
for p in $(pidof icinga2); do echo -e "$p\n" && ps -ef | grep $p && echo && cat /proc/$p/limits | grep 'open files' && echo; done

for p in $(pidof icinga2); do echo -e "$p\n" && ps -ef | grep $p && echo && lsof -p $p && echo; done

```

Cheers,
