I'm unable to reproduce it, but I do have core saved, if someone wants me to do some post-mortem investigation. Box is quad-core amd64 running -current as of May 8th. The crash was observed when I attempted to interrupt parallel make that did access fair amount of stuff over NFS. --Artem Tracing pid 12 tid 100012 td 0xffffff0004460390 _mtx_lock_sleep() at _mtx_lock_sleep+0x4e clnt_dg_soupcall() at clnt_dg_soupcall+0x168 sowakeup() at sowakeup+0xd9 udp_append() at udp_append+0x20b udp_input() at udp_input+0x6b5 ip_input() at ip_input+0xaa swi_net() at swi_net+0xf7 intr_event_execute_handlers() at intr_event_execute_handlers+0x100 ithread_loop() at ithread_loop+0x8e fork_exit() at fork_exit+0x118 fork_trampoline() at fork_trampoline+0xe --- trap 0, rip =3D 0, rsp =3D 0xfffffff800063d40, rbp =3D 0 --- 2009/5/11 Pav Lucistnik : > panic: mtx_lock() of destroyed mutex @ /usr/src/sys/rpc/clnt_vc.c:953 > cpuid =3D 2 > KDB: enter: panic > [thread pid 0 tid 100029 ] > Stopped at =A0 =A0 =A0kdb_enter+0x3d: movq =A0 =A0$0,0x3f5fb8(%rip) > db> bt > Tracing pid 0 tid 100029 td 0xffffff00018e1000 > kdb_enter() at kdb_enter+0x3d > panic() at panic+0x17b > _mtx_lock_flags() at _mtx_lock_flags+0xc5 > clnt_vc_soupcall() at clnt_vc_soupcall+0x273 > sowakeup() at sowakeup+0xf8 > tcp_do_segment() at tcp_do_segment+0x23c9 > tcp_input() at tcp_input+0x9ec > ip_input() at ip_input+0xbc > ether_demux() at ether_demux+0x1ed > ether_input() at ether_input+0x171 > em_rxeof() at em_rxeof+0x201 > em_handle_rxtx() at em_handle_rxtx+0x4b > taskqueue_run() at taskqueue_run+0x96 > taskqueue_thread_loop() at taskqueue_thread_loop+0x3f > fork_exit() at fork_exit+0x12a > fork_trampoline() at fork_trampoline+0xe > --- trap 0, rip =3D 0, rsp =3D 0xffffffff240a6d40, rbp =3D 0 --- > > The box is in kdb on serial console for now.
