From: Kenneth Vestergaard Schmidt To: bug-followup@FreeBSD.org, dan@more.net Cc: Subject: Re: kern/113823: [panic] Fatal trap 12: page fault while in kernel mode Date: Tue, 26 Jun 2007 11:31:21 +0200 Hello. We're experiencing the same problems, too, on a lot of our Sun Fire x2100 (AMD64) servers. We've experienced it on web-servers (mostly just Apache and postfix), and machines with 5-10 jails, running Apache, MySQL, postfix, and the likes. The problem has appeared on everything from 6.2-RELEASE to 6.2-p5. machine amd64 cpu HAMMER options SMP options COMPAT_IA32 using em(4), gmirror and pf(4). It seems kern/111458 is related, too. We have boxes to spare, if anything needs testing, but I haven't found a way to reproduce it yet, besides just waiting. It might be related to load, or number of processes, but I have no hard evidence.
