[erlang-questions] Intermittent failures connecting C hidden nodes

I had a situation where erlang listener on a particular node would refuse 
any new, whilst maintaining existing connections. How did we fix that... 
Well, we've recompiled the ERTS for that particular OS patch level, and I do 
not recall having such a problem ever since. In other words, it might be 
that you're looking for a problem/solution in a wrong place. The question 
you should ask: does the problem always occurs on a particular server. If 
so -- find what is the difference (OS patch level) between this server and 
others, and if there is any, verify that the run-time (ERTS) has been build 
for that particular machine.

This is a brave assumption, and occasionally a wrong one... I suggest that 
you do recompile & re-link using 3.5.5.3 if your target is R11B3, if nothing 
else, just to eliminate this as a potential cause.
