Actually the only change i made to this system (running flawless close to two years) is upgrading to latest 8.* from sources less than month ago. but still - even assuming that system update introduced a bug - i cannot understand why it happens at sunday when it is least loaded. Only rarely visited WWW that time, few mails, and no load present as in work days. since last crash i inserted pendrive and set it as dump device (FreeBSD doesn't seem to reliably crashdump to gmirrored+geli devices, i don't have others available). but as you see it halted, no crash dump
