Please upgrade to a more recent version. The one you're using now is  
well over five years old and is no longer supported.

Most likely because there was a problem with the communication with  
the driver socket. There was an error in the staleness logic in older  
versions of the 'upsd' server, which caused it to declare the driver  
stale after the first failure. Upgrade.

No. NUT errs on the side of caution. If the UPS is known to be on  
battery and there is a communication problem with the driver socket,  
the system shuts down. You can't (and shouldn't change) that.
