Anyway, if/when you succeed collecting some strace of the server 
processes, please let me know (though putting a full one available might 
not be wise thing like I said earlier). After I thought it a bit, it might 
be enough the start the strace with -p for all server processes of a 
service during a stall and then resolve it after some amount of waiting 
with nmap (and hope that strace doesn't resolve it by interfering 
something relevant :-), you will see that from the fact that it resolves 
without nmap then). That would probably reveal if the processes where 
waiting in accept() or not, and if not, where they were.

	I got a stall, tried to use strace but even strace couldn't
trace nothing. Everything which uses some kind of network connection is
stalled (or because everything is stalled, strace couldn't trace
anything).
	
	I'll try to leave strace running all the time, but I'm afraid
it could prevent the stall. Anyway, I'll test and return soon.
