do_page_fault() on 712/60 running 2.4.9-pa22

Hello all,

I've seen this several times before (& posted to the list as well), but can't figure out what might be causing it or how to duplicate it. I noticed today that ~ 3:30 AM EDT, several do_page_fault() errors were reported (kern.log attached).

This is running 2.4.9-pa22 kernel which I build a few days ago from CVS. Earlier, I had thought that the problem might be related to swapping, but couldn't duplicate the problem at will.

# cat /proc/version 
Linux version 2.4.9-pa22 (root@dlarry) (gcc version 3.0.2 20010825
(Debian prerelease)) #7 Fri Sep 21 16:37:05 EDT 2001

Can anyone offer a suggestion as to how to investigate this further? Would updating glibc help?

Thanks,

-chuck
