You are at the point to change your OS. Enter the world of Debian/Linux. 
Move NOW! :-))

We discussed this problem a few days ago on this list. RedHat changes in 
RH 9 standard kernel to POSIX thread library for Linux. You have two 
choices:

1) Upgrade from RedHat 9.0 standard kernel 2.4.20-8 to 2.4.20-13.9 and 
upgrade your glic and glic-common to 2.3.2-27.9. Be carefull at this 
point and choose the right kernel and(!) glibc for your processor type. 
If you have an i686, but install i386 packages, your system will useless 
FOR EVER.

see http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=88456

You can download rpm packages from redhat errata website or via ftp from 
ftp.redhat.de/pub/redhat/updates/9/en/os

Installing RPMs:

   rpm -Uvh glic-2.3.2-27.9-xxx glibc-common-2.3.2-27.9.xxx
   rpm -Uvh kernel-2.4.20-13.9-xxx

Reboot the system.

2) Disbale POSIX thread library in the standard kernel by setting 
"export LD_ASSUME_KERNEL=2.4.1" in the bash you use to start zope.

Note: Since RedHat 8.0 use "-m" option for ps to see all threads, eg. ps 
-aum
