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,
below find ksymoops outputs (2 slightly different ones):
the first one:
