Hi all, Over the last weekend, I saw a couple of crashes on a 10.3-system acting as filtering bridge with pf that all looked like this: --- Unread portion of the kernel message buffer: Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0xe fault code = supervisor write data, page not present instruction pointer = 0x20:0xffffffff81c45fb9 stack pointer = 0x28:0xfffffe01eeaa54a0 frame pointer = 0x28:0xfffffe01eeaa55d0 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 = 12 (irq275: igb2:que 0) trap number = 12 panic: page fault cpuid = 0 KDB: stack backtrace: #0 0xffffffff8098e390 at kdb_backtrace+0x60 #1 0xffffffff80951066 at vpanic+0x126 #2 0xffffffff80950f33 at panic+0x43 #3 0xffffffff80d55f7b at trap_fatal+0x36b #4 0xffffffff80d5627d at trap_pfault+0x2ed #5 0xffffffff80d558fa at trap+0x47a #6 0xffffffff80d3b8d2 at calltrap+0x8 #7 0xffffffff81c2c4c8 at pf_test+0x1c8 #8 0xffffffff81c3e07d at pf_check_in+0x1d #9 0xffffffff80a24ef4 at pfil_run_hooks+0x84 #10 0xffffffff81c148e3 at bridge_pfil+0x363 #11 0xffffffff81c153a5 at bridge_forward+0x1c5 #12 0xffffffff81c13c55 at bridge_input+0x555 #13 0xffffffff80a1c05a at ether_nh_input+0x2ba #14 0xffffffff80a24092 at netisr_dispatch_src+0x62 #15 0xffffffff804f859c at igb_rxeof+0x60c #16 0xffffffff804f8c41 at igb_msix_que+0x121 #17 0xffffffff8091c99b at intr_event_execute_handlers+0xab --- Before that happening, the system was fine for about 6 months. Over the weekend I saw about 10 identical crashes and subsequent reboots like this (with sometimes only a few minutes of operation between). Running out of other ideas, I updated the system to latest release (-p7), and up to now it didn't happen again. Any ideas what might be causing this? cu Gerrit
