Today, after I updated my mailcow installation, I noticed a high CPU load on one of the CPU cores, caused by the following running command: python3 -u /server.py
I saw that this is coming from the netfilter-docker image, so I checked the log, maybe one of you could help me out with this:
netfilter-mailcow_1 | Clearing all bans
netfilter-mailcow_1 | Initializing mailcow netfilter chain
netfilter-mailcow_1 | Traceback (most recent call last):

netfilter-mailcow_1 | Error 113 connecting to 172.22.1.249:6379. Host is unreachable. - trying again in 3 seconds
netfilter-mailcow_1 | Clearing all bans
I tried to restart the server and the docker image itself, it didn’t help. I can still access the mailcow control panel and email is still working.
Operating System: Debian GNU/Linux 9 (stretch)
Kernel: Linux 4.9.0-12-amd64
Many thanks.
