Re: APC UPS causing crashes?

APC Back-UPS 650/750, USB signalling lead.
No specialist software, standard Windows power-management settings in

Both of these servers have shown problems with intermittent rebooting
since the above type of UPS was connected. The 2000 server very
occasionally, the 2003 daily. Since taking the UPS away the 2003 has
been stable (touch wood!)

A third server running Debian Linux also had issues last year with a
memory-leak which was traced to the (distro's own) UPS-monitoring
applet. Same UPS model. The Debian guys didn't seem to think there
were any known bugs with their UPS-monitoring daemon.

Doesn't seem to be power-loss as such, more like an issue with the USB
interface. A crash debug suggested there had been a blusecreen before
the reboot, but was inconclusive as to the cause. I can live without
the powerfail signalling (especially if it causes crashes, talk about
a useless piece of security!) but it would be better to find a
resolution.

APC site doesn't really offer any hints, so just wondered if anyone
in here had encountered this?

I never use these without PowerChute, so I'm not sure what to say - I have
no issues with anything at all - using SmartUPS 1400/1500/etc on W2k, W2003,
alike. Are you certain those UPS units were spec'd out with sufficient power
for your hardware? 650/750 isn't something I'd use for most modern servers.

What's the reason you're using the far more limited native Wkindows UPS
management?
