It looks like lots of threads banging on fork() and that they are all waiting on an exclusive lock of allproc_lock while holding a shared lock of proctree_lock (except for the 1 thread currently doing a fork that is on a run queue because it was preempted by IRQ 0 which kicked off softclock). Can you get 'ps' output? -- John Baldwin <jhb_at_FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.orgReceived on Tue Feb 08 2005 - 17:32:14 UTC
