RE: Sudden and unexplained reboots
Folks, After spending like an hour next to the server itself, I saw it crash with a 'page fault' panic. All speculations about fans and CPU over-heating is irrelevant as the server's cooling infrastructure is working perfectly (2 fans for CPU, 2 fans for disks, 2 external fans, 2 fans for the power supplies, and all are working.) The panic's details are as follows: Fatal trap 12 = page fault while in kernel mode fault virtual address = 0xbfc407fc fault code = supervisor write, page not present instruction pointer = 0x8:0xc021d5e3 stack pointer = 0x10:0xfbf8ae20 frame pointer = 0x10:0xfbf8ae2c code segment= base 0x0, limit 0xf, type 0x1b DPL 0, pres 1, def32 1, gran 1 processor eflags= interrupt enabled, resume, IOPL = 0 current process = 45671 (ftpd) interrupt mask = none trap number = 12 panic = page fault syncing disks... 56 2 Done Uptime: 51m35s Anyone knows what the hell is going on? By the way, is there a way to dump the panic's message to disk automatically when a panic occurs? Is there a log somewhere when a panic occurs? /Noor | -Original Message- | From: Charles Sprickman [mailto:[EMAIL PROTECTED] | Sent: Wednesday, June 04, 2003 10:21 PM | To: Don Lewis | Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED]; | [EMAIL PROTECTED] | Subject: Re: Sudden and unexplained reboots | | | On Wed, 4 Jun 2003, Don Lewis wrote: | | > I'd also check to make sure that all the fans are operational and | > something isn't overheating. | | I ran into two boxes with the same bad CPU fans.

Also, obviously, make sure that you're not getting any power surges or anything of the sort; basically anything hardware-related that could possibly cause a reboot. If you're plugged into a series-connected outlet, I would advise to try a different outlet. If you're plugged into a UPS, make sure that the load on it is not too high. -- Bosko Milekic [EMAIL PROTECTED] [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
