FWIW, we once experienced a particularly confusing kind
of false positive with the net ticks. This happened during
/very low/ network load. The problem was a bug in the
internal communication paths of the AXD 301, which caused
some packets to be lost, and the max_rexmit_interval
setting happened to be higher than the net_ticktime.
So basically, the TCP stack could end up setting the
retransmit time to longer than Erlang's detection time
(which we had set to 10 seconds.)
