When the UPS starts to run on Battery, upsmon notifies upssched, and upssched runs an "onbatt script", which sends out an alert every 15 seconds via wall. When the UPS is put back on line, upsmon acknowledges this change (via WALL). However, upssched does not get notified properly, so the onbatt script continues to send alerts. About 45 seconds later, upssched acknowledges the UPS change, and disengages the onbatt script. I checked syslog, and I found these upssched error messages during that 45 second delay: Jul 21 10:23:55 simnet-alic upsmon[3917]: UPS APC@localhost on battery Jul 21 10:23:55 simnet-alic upssched[3925]: Timer daemon started Jul 21 10:23:55 simnet-alic upssched[3925]: New timer: onbatt (5 seconds) Jul 21 10:24:00 simnet-alic upssched[3925]: Event: onbatt Jul 21 10:24:50 simnet-alic upsmon[3917]: UPS APC@localhost on line power Jul 21 10:24:52 simnet-alic upssched[3948]: read confirmation failed, trying again Jul 21 10:25:22 simnet-alic last message repeated 15 times Jul 21 10:25:22 simnet-alic upssched[3948]: Executing command: onpower Does anyone know why I'm running into this problem? -Rob -------------- next part -------------- An HTML attachment was scrubbed...
