Additional info:

Comment 1 Arjan van de Ven 2002-11-10 14:02:28 UTC

which kernel version is this ?

Comment 2 Need Real Name 2002-11-10 14:23:36 UTC

2.4.9-13

Comment 3 Need Real Name 2002-11-10 14:27:12 UTC

I see, that there is only 4 Mb free memory. May be this is a cause?

Comment 4 Bugzilla owner 2004-09-30 15:40:11 UTC

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
