[Nut-upsuser] Data Stale at random intervals

[Daniel Shields]

Just an update, these messages are in the syslog when nut is no longer able to communicate with the server:

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.

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!

gzipped and resent for the rest of the list.

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