Subject: kernel oops
Date: Mon, 8 Oct 2001 14:59:33 +0200	[thread overview]
Message-ID: <004501c14ff9$13e60fe0$6f00000a@compfort> (raw)

Hello,
i am recently experiencing kernel errors with httpd process,
the software used:

apache 1.3.18 running in chroot environment,
self built kernel 2.4.10,
glibc 2.2.2, gcc version 2.96, binutils 2.10)

the problem is semi-repeatable, that is it happens almost always after a few
minutes of running
that httpd, but is triggered either by running CGI scripts or trigerring
apache 40x errors.

the hardware used is P200 MMX, 64 megz of ram, tx chipset

if you need any further information i will be happy to help,

ksymoops outputs:
