Hello together, i got the an Simular Issue after an Upgrade from the 2.0.0p24 to 2.1.0p2 RAW Edition.

Tried to adjust the Time in here /etc/systemd/system/multi-user.target.wants/cmk-agent-ctl-daemon.service with an StartLimitInterval=30, but no changes.

Is the Post here OK or should i open a new one ?
