I will try cmdebug the next time it hangs. When this happens I can ssh 
into the machine but a graceful restart is impossible because it will 
not umount /afs
Also if I try to ls /afs that will hang because there is nothing there 
anymore.
This is a web based front end server running UofM's Mfiles app and 
apache modwaklog.
This gives users access to their home AFS volumes via a web browser.
When it wedges again I will see if I can get apache to shut down and 
then try a restart of the AFS client.
