I have 3 containers running Ubuntu 22.04. The host is also Ubuntu 22.04.
Those 3 containers are running Apache, which runs well in the beginning, but then after a while (could be a few hours or a few days), it just stops serving pages. Each time another container fails.
The service is still running, port 443 is still being listened to by Apache, and the logs don’t show anything relevant.
The only way to get out of this situation is to restart Apache.
It could very much not be related to LXD, but it seems odd that it occurs with all the containers.
Any suggestions or guiding questions would be helpful.
