Sorry about the html posting, it seems that Mozilla M13 decided to rape my
message. I hate html postings just as much as you do (thank god for
procmail filters), and will send this one using pine so Mozilla doesn't
try to rethink my e-mail for me.
Kernel:
=======
FreeBSD karma.afterthought.org 4.0-CURRENT FreeBSD 4.0-CURRENT #0: Mon Feb
14 23:00:42 GMT 2000
[EMAIL PROTECTED]:/usr/src/sys/compile/KARMA i386
Background:
============
3 users. One with X running <me>, and two users running breakwidgets
<binary testing script>, which make use of a minimized version of the
"killall" perl script which reads procfs.
This crash appears to be the old one where when two processes read procfs
simultaneously, ugly things can happen. mdillon described this in more
depth to me once but I've since lost the e-mail. <I posted similar crash
reports in late November & early december>. He suggested having my
programs "lock" procfs reads so only one could do it's killall function at
a time. Unfortunatly, the binary testing script is very time sensitive and
this would slow things down <my current run-through is about 48 hours
paralleled on 4 machines>
The kernel is a GENERIC one with ipv6, softupdates, and pcm added to it.
