I was running 4.6.1 for a while, and all was stable. The box had about 40 days uptime since going live. I then moved up to 4.6.2 on Sunday afternoon, since there seemed to be general concern over stability with 4.6.1. On Sunday evening at 22:21 (about 3 hours after completing the upgrade from 4.6.1) the box crashed and restarted of it's own accord. And it just did the same again about half an hour ago (11:46 Tuesday). I have included extracts from /var/log/messages below. The significant part seems to be: --- Fatal trap 12: page fault while in kernel mode --- Unfortunately this means nothing to me :( I notice that the "current process" on these two occasions is NOT the same (rateup on Sunday, perl today). But I have no idea whether that is significant at all. Any advice would be VERY MUCH appreciated! Also, please let me know what other info would be useful in helping resolve this problem. /var/log/messages from Sunday evening: --- Aug 18 22:21:05 obelix /kernel: Aug 18 22:21:05 obelix /kernel: Aug 18 22:21:05 obelix /kernel: Fatal trap 12: page fault while in kernel mode Aug 18 22:21:05 obelix /kernel: fault virtual address = 0x0 Aug 18 22:21:05 obelix /kernel: fault code = supervisor read, page not present Aug 18 22:21:05 obelix /kernel: instruction pointer = 0x8:0xc10c675d Aug 18 22:21:05 obelix /kernel: stack pointer = 0x10:0xcc8d2b94 Aug 18 22:21:05 obelix /kernel: frame pointer = 0x10:0xcc8d2ba8 Aug 18 22:21:05 obelix /kernel: code segment = base 0x0, limit 0xfffff, type 0x1b Aug 18 22:21:05 obelix /kernel: = DPL 0, pres 1, def32 1, gran 1 Aug 18 22:21:05 obelix /kernel: processor eflags = interrupt enabled, resume, IOPL = 0 Aug 18 22:21:05 obelix /kernel: current process = 17195 (rateup) Aug 18 22:21:05 obelix /kernel: interrupt mask = none Aug 18 22:21:05 obelix /kernel: trap number = 12 Aug 18 22:21:05 obelix /kernel: panic: page fault Aug 18 22:21:05 obelix /kernel: Aug 18 22:21:05 obelix /kernel: syncing disks... 141 118 116 113 106 101 91 71 56 41 39 38 38 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Copyright (c) 1992-2002 The FreeBSD Project.
