It looks like I've got live lock on my router. It acts as router, but physical console (serial one) and ssh connection are stalled and don't react on keypresses. After two or three minutes everything unfreeze, then freeze again... After unfreeze here are messages from "nut" that connection with UPS is lost (UPS is connected to other host in network) and re-established. I don't understand how to debug such situation :) uname -a is: FreeBSD gateway.home.serebryakov.spb.ru 10.0-CURRENT FreeBSD 10.0-CURRENT #1 r239228: Mon Aug 13 13:07:52 MSK 2012 root@vmware-c-32.home.serebryakov.spb.ru:/usr/obj/nanobsd.gateway-net5501/data/src/sys/NET5501 i386 Scheduler is ULE. -- // Black Lion AKA Lev Serebryakov
