I have seen a very similar problem on file servers, in my case an NFS workgroup 
server. I thought it was due to down level 3.8.13-fc17 kernel, not scheduled for 
upgrade for a few months yet, probably over Labor Day weekend.

However, existing connections on the machine also will respond to ENTER with a 
newline, but any connand requiring a new process hangs. It behaves as if the 
machine was out of processes, but I traced processes every few minutes and saw 
no buildup.

In addition, the machine hosts a virtual machine which continues to work just 
fine. Does any of this match additional issues you didn't mention or haven't 
checked?

May or may not be related, we have a console open on the machine and can verify 
the odd behavior.
