Tough nut to crack.

I'd recommend watching the server-side CPU load during the hang.  Is it
working hard, or just idle?

If idle, perhaps use strace on the server to see what system call it is
waiting on.  That might give a clue.  If it waits on a socket or file
handle, that may point to something as well.
