There is an update for clumanager https://rhn.redhat.com/errata/RHBA-2007-0041.html
The file is available here: http://bender.it.swin.edu.au/centos-3/csgfs/i386/clumanager-1.2.34-3.i386.rp...
This file is signed with my jnewbigin-csgfs@ict.swin.edu.au and needs to be resigned with the CentOS-3 key.
(bender is now a virtual machine and may not always be available but it is currently running).
