"Linux hangs" is a bit nebulous - is this a hang of the client shell 
running the process or is it a total deadlock of the kernel?  You can 
check this by using a virtual terminal if you are using tty console 
access.

Have you tried cycling the fileserver process (bos shutdown, wait for 
client to timeout then startup again)?  I have a persistent unsolved 
issue with 1.2.11 which Derek has been helping me debug (very slowly) 
and I'm curious to know if your hangups might be of similar origin.

Also you should try running 'strace' on the client to see what system 
call, if any, the hangup is associated with.
