>Number: 11266 >Category: kern >Synopsis: frequent crashes with "Page fault, fatal trap in kernel" >Confidential: no >Severity: serious >Priority: high >Responsible: freebsd-bugs >State: open >Quarter: >Keywords: >Date-Required: >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Wed Apr 21 14:00:01 PDT 1999 >Closed-Date: >Last-Modified: >Originator: Nickolai Zeldovich >Release: FreeBSD 3.1-RELEASE i386 >Organization: Craig's DATA Exchange >Environment: PentiumII-266, FreeBSD-3.1, running Diablo news server with 4 IDE disks on two buses, using CCD to stripe. Mostly standard kernel config except for maxusers and memory parameters. >Description: Every so often (at least once a week) our news box crashes with error message "Page fault, fatal trap in kernel". When this happens, the machine remains pingable and I can telnet to it, and it accepts the connection, yet nothing comes up (e.g. login prompt). Same for trying to connect to ssh or NNTP. Although this sounds like a problem with NMBCLUSTERS being set too low, the kernel has this set at 3072 and does not seem to be a problem (netstat -m never reports peak being above 1000). >How-To-Repeat: Have not determined a precise way to crash this yet. Our news machine keeps crashing every week or so with this error. Is this a known or suspected bug in the 3.1 kernel? >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
