Logs on secondary appliance show error after Config Cleaner runs

Hi,

We have 2 Checkmk Appliances, in distributed monitoring. Each appliance is in a different geographic location. For the last 2 days we have seen warnings on the log files for the secondary appliance.

2024-02-28 22:17:23 [5] [core 812] [config cleaner] removed dead configuration directory “/omd/sites/mysite/var/check_mk/core/helper_config/16664”
2024-02-28 22:17:47 [4] [client 0] error: client connection terminated: timeout
2024-02-28 22:17:52 [4] [client 7] error: client connection terminated: timeout
2024-02-28 22:17:57 [4] [client 6] error: client connection terminated: timeout
2024-02-28 22:18:02 [4] [client 8] error: client connection terminated: timeout
2024-02-28 22:18:07 [4] [client 9] error: client connection terminated: timeout
2024-02-28 23:16:30 [5] [core 812] Reloading configuration on-the-fly…

the above is an example and a similar error in the logs happened about 1 minute before the above example.

We are unsure what is causing this error. Anyone have any ideas?

Thanks in advance :slight_smile:
