Hello list members,
I am running NUT 2.0.1 on an OpenBSD 3.8 system, using the OpenBSD port for net-snmp-5.1.2p2. The UPS is connected via an AP9606 Web/SNMP card with current firmware, and the LAN. All goes well for a long time, usually more than one month. Then the system starts spitting messages about losing communications with the UPS. A second message about reconnecting follows immediately. The messages are sometimes coming at a fast rate, faster than the 300 seconds specified for NOCOMMWARNTIME in upsmon.conf. A reboot of the computer running NUT (the only computer running NUT) does not fix it, so I assume that there is something going on with the UPS or the UPS network card.
If this is not a known problem, I would be happy to do some guided sleuthing to track it down. However, I have no clue where to look.
Any pointers would be much appreciated.
George
The system log messages look like this:
Jan 4 10:57:00 z9 upsd[12613]: Data for UPS [ap9606-srv] is stale - check driver
Jan 4 10:57:02 z9 upsd[12613]: UPS [ap9606-srv] data is no longer stale
Jan 4 10:59:02 z9 upsd[12613]: Data for UPS [ap9606-srv] is stale - check driver
Jan 4 10:59:02 z9 upsd[12613]: UPS [ap9606-srv] data is no longer stale
The output from upsmon -D (with console messages interspersed) follows
/usr/local/ups/sbin >> ./upsmon -D
