[Nut-upsuser] frequent COMMBAD/COMMOK notifications (every 3-6 minutes)

[Lee Damon]

I'm running nut-2.8.0-3.el8.x86_64 on CentOS Stream 8 talking with an
APC Smart-UPS RT 5000 RM XL via a Network Management Card AP9619 (version
A10). Up to today I would receive occasional COMMBAD messages, then 5
minutes later I'd see a COMMOK.Maybe 1 or two a day.

Today I updated the firmware on the AP9619 from 3.7.2 to SUMX 3.9.3 and AOX
3.9.4, the most recent releases available for the card.

Now I am seeing COMMBAD, then a minute later COMMOK, roughly every 3-6
minutes. I don't think it's a network problem:

1000 packets transmitted, 999 received, 0.1% packet loss, time 1000727ms
rtt min/avg/max/mdev = 2.503/3.554/78.377/2.519 ms

So, is there something I can do to figure out what's going on or failing
that is there a setting I can tweak that says "If you lose comm with the
UPS, wait 6 minutes before complaining about it"?

thanks,
nomad
