Not yet. You once said accept() fails, but your setup starts to diverge
after recv() (by doing a send()). What errors do which services return?
Did you check that you have sufficient buffers configured for your
network load (RTNET_RTIOC_EXTPOOL)?

Again, it's _much_ easier if you stick this simple setup in a generic
test case.
