I'm running a very small Openfire server (5 users) on a Raspberry Pi. 1-3 times per day, the server disconnects all users and is inaccessible via the admin console. I can see that the process is still running, so it's not crashing outright. Restarting the service brings it back to life.
Unfortunately, there's nothing in the logs -- timestamps don't correspond to the times (or even days) when the server stops responding. It also doesn't seem to be a memory issue, as I've been monitoring memory both in Linux in general and within the Openfire admin console (when it's responding). I never see it get anywhere near maxed out.
If anyone has a suggestion, I'd appreciate it. I'm also wondering if there's a way to log more information somehow, to try and narrow in on this. Without logs, I'm not sure how to go about debugging the problem. Thanks.
Openfire Version: 4.0.0 (and previously 3.10.3)
OS: Raspbian (Debian)
