Hi ! Sometimes (once a week approximately) I have a problem with the same symptoms described here on SMP FreeBSD 6.2-STABLE with dual AMD Opteron(tm) Processor 850: http://www.freebsd.org/cgi/query-pr.cgi?pr=104406&cat= Sometimes (apparently when CPU load suddenly goes up) all processes that interacts with disk gets stuck in "ufs" state, but in my case SIGSTOP/SIGCONT seemingly does not help. uname -a output: FreeBSD serv2.vsi.ru 6.2-STABLE FreeBSD 6.2-STABLE #2: Sat Mar 3 01:59:08 MSK 2007 oleg@serv2.vsi.ru:/usr/obj/usr/src/sys/serv2 i386 dmesg.boot: Copyright (c) 1992-2007 The FreeBSD Project.
