AIX should not have to be rebooted for this to happen. For debug, I  
would change the shell to a real shell; change the fsize to 600 or  
something small; logout and then login(as root and then su or just as  
the user) and try to make large files and verify limits. Ping me off  
list for more debugging unless people consider this on topic.
