I have noticed that too. The UPSes I monitor (via serial interface) lose
connection every couple of days (random) and reconnect almost immediately.
I suspect that this is due to a glitch in the PING/PONG between upsd and
driver. Currently, the server is not really robust in this aspect, since
right after retrying to PING a driver (if it failed to respond the first
time), it will be declared stale (without allowing it time to reply). This
needs to be changed, so that there is time to retry at least once allowing
enough time for processing it without declaring the driver stale.
