Hi I have the following recurring panic on all my heavily network loaded -CURRENT routers. The current process is always different. Gleb, can you please chime in with what you've managed to uncover. Unread portion of the kernel message buffer: processor eflags = interrupt enabled, resume, IOPL = 0 current process = 21363 (kgdb) trap number = 12 panic: page fault cpuid = 1 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2a/frame 0xffffff846b4de530 panic() at panic+0x13d/frame 0xffffff846b4de630 trap_fatal() at trap_fatal+0x290/frame 0xffffff846b4de690 trap_pfault() at trap_pfault+0x21f/frame 0xffffff846b4de6f0 trap() at trap+0x2b4/frame 0xffffff846b4de830 calltrap() at calltrap+0x8/frame 0xffffff846b4de830 --- trap 0xc, rip = 0xffffffff8044872d, rsp = 0xffffff846b4de8f0, rbp = 0xffffff846b4de910 --- __mtx_lock_sleep() at __mtx_lock_sleep+0x5d/frame 0xffffff846b4de910 selfdfree() at selfdfree+0xef/frame 0xffffff846b4de930 sys_poll() at sys_poll+0x332/frame 0xffffff846b4dead0 amd64_syscall() at amd64_syscall+0x572/frame 0xffffff846b4debf0 Xfast_syscall() at Xfast_syscall+0xf7/frame 0xffffff846b4debf0 --- syscall (209, FreeBSD ELF64, sys_poll), rip = 0x80160670a, rsp = 0x7fffffffcc68, rbp = 0 --- Uptime: 3d5h49m17s Dumping 2580 out of 16368 MB:..1%..11%..21%..31%..41%..51%..61%..71%..81%..91% #0 doadump (textdump=1) at /usr/src/sys/kern/kern_shutdown.c:264 264 if (textdump && textdump_pending) { (kgdb) #0 doadump (textdump=1) at /usr/src/sys/kern/kern_shutdown.c:264 #1 0xffffffff8045a424 in kern_reboot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:447 #2 0xffffffff8045a927 in panic (fmt=<value optimized out>) at /usr/src/sys/kern/kern_shutdown.c:754 #3 0xffffffff8061e950 in trap_fatal (frame=0xc, eva=<value optimized out>) at /usr/src/sys/amd64/amd64/trap.c:872 #4 0xffffffff8061ecbf in trap_pfault (frame=0xffffff846b4de840, usermode=0) at /usr/src/sys/amd64/amd64/trap.c:789 #5 0xffffffff8061f074 in trap (frame=0xffffff846b4de840) at /usr/src/sys/amd64/amd64/trap.c:463 #6 0xffffffff806088ef in calltrap () at /usr/src/sys/amd64/amd64/exception.S:228 #7 0xffffffff8044872d in __mtx_lock_sleep (c=0xffffff8006e551e8, tid=18446741875506397184, opts=<value optimized out>, file=<value optimized out>, line=0) at /usr/src/sys/kern/kern_mutex.c:425 #8 0xffffffff804a574f in selfdfree (stp=<value optimized out>, sfp=0xfffffe02bbf92690) at /usr/src/sys/kern/sys_generic.c:1524 #9 0xffffffff804a6e82 in sys_poll (td=0xfffffe0030e1c000, uap=0xffffff846b4deb70) at /usr/src/sys/kern/sys_generic.c:1369 #10 0xffffffff8061e2b2 in amd64_syscall (td=0xfffffe0030e1c000, traced=0) at subr_syscall.c:134 #11 0xffffffff80608bd7 in Xfast_syscall () at /usr/src/sys/amd64/amd64/exception.S:387 #12 0x000000080160670a in ??
