Severity: important

Hi,

One of my machines connected as a secondary went AWOL. It was shut down
after this sequence of events in the log:

May 29 23:19:15 mysecondary nut-monitor[4075438]: UPS 
[email protected]: calibration in progress
May 29 23:19:15 mysecondary nut-monitor[155306]: Network UPS Tools upsmon 2.8.1
Jun 01 13:56:08 mysecondary nut-monitor[4075438]: Poll UPS 
[[email protected]] failed - Server disconnected

[[email protected]] was last known to be calibrating and currently 
is not communicating, assuming dead

power-fail shutdown
Jun 01 13:56:08 mysecondary nut-monitor[4075438]: Auto logout and shutdown 
proceeding

Jun 01 13:56:08 mysecondary nut-monitor[2735912]: Network UPS Tools upsmon 2.8.1
Jun 01 13:56:13 mysecondary nut-monitor[4075438]: Network UPS Tools upsmon 2.8.1

The primary at myprimary.domain.tld was idle throughout this time.
The secondary config is:

% sudo cat /etc/nut/nut.conf 
MODE=standalone
% sudo cat /etc/nut/upsmon.conf 
MONITOR [email protected] 1 mysecondary censored secondary
SHUTDOWNCMD "/sbin/poweroff"

This sounds like it could be another manifestation of something like
https://bugs.debian.org/1056190 /
https://github.com/networkupstools/nut/issues/2168 ?

Either way, it seems to cause arbitrary downtime, so we probably shouldn't
have this in stable?

Please have a look. TIA.
