Below is the proper format you should see. The line with a period at the 
end is required to show that the list command has completed. If you do 
not get that, then the server hasn't successfully completed the list 
command to accept new commands. Check your logs for any mention of the 
connection and errors that might have generated. If you are using NFS, 
there are several issues with locking that can be problematic.

If you are getting the '.' line, then try other commands besides quit. 
It is important to determine if the code is ignoring input or if it has 
a problem with the actual quit code. Also, I notice you mentioned 
several hours. It would be useful to know if this occurs on startup or 
if it fails over time. It is also useful to know if it effects all 
accounts or just some of the active accounts. It is also useful to know 
if there are people currently logged in on those accounts when you 
perform your test.
