Dear list, I hope I am posting this to the correct list - if not, I apologize (and please advise where to post this instead).
Today I experienced a kernel panic on a (physical) server, running Freebsd 11.2-RELEASE-p7 with GENERIC kernel, ZFS root: Fatal trap 9: general protection fault while in kernel mode cpuid = 0; apic id = 00 instruction pointer = 0x20:0xffffffff82299013 stack pointer = 0x28:0xfffffe0352893ad0 frame pointer = 0x28:0xfffffe0352893b10 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 9 (dbuf_evict_thread) trap number = 9 panic: general protection fault cpuid = 0 KDB: stack backtrace: #0 0xffffffff80b3d577 at kdb_backtrace+0x67 #1 0xffffffff80af6b17 at vpanic+0x177 #2 0xffffffff80af6993 at panic+0x43 #3 0xffffffff80f77fdf at trap_fatal+0x35f #4 0xffffffff80f7759e at trap+0x5e #5 0xffffffff80f5808c at calltrap+0x8 #6 0xffffffff8229c049 at dbuf_evict_one+0xe9 #7 0xffffffff82297a15 at dbuf_evict_thread+0x1a5 #8 0xffffffff80aba093 at fork_exit+0x83 #9 0xffffffff80f58fae at fork_trampoline+0xe I have used "crashinfo" utility to generate the text file which is available at this URL: http://www.ocpea.com/dump/core.txt At the time of the crash, the server was probably under more intensive I/O load (scheduled backup with rsync). This is a production server, so naturally, all advice is deeply appreciated. :) Kind regards, Jurij _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
