Start by checking if there are problems with the TCP connections
themselves. It could be an Erlang-problem, but you need to investigate at a
lower level first. Networks tend to be evil. Erlang usually operates quite
okay without tuning of these settings. Which leads me to suspect there is
something else going on somewhere. A simple 'netstat -s' can sometimes show
something ugly as well.
