<p>The server reconnects, but can't communicate due to the Data Stale. I get the same result from trying to restart the nut-server service manually. I have to stop and restart the service and it will work for a couple hours up to ~ 24 sometimes.</p>

Here are the results of a restart as well as a stop/start. Seems like it may be the server? I tried to run the nut-server service with gdb, but no luck getting it to work so far. Thanks!<br>

Can you elaborate on how it quit? I don't see any error messages to that effect.<br>
