net_kernel:set_net_ticktime(TickTime [, TransitionPeriod])

The default tick timeout is 45 < T < 75, with TickTime
being 60 seconds.

See http://www.erlang.org/doc/man/kernel_app.html

Normally, and especially for systems where response time
is an issue, the default ticktime is too long - not too short.
If you have network connections that are not responding within
at least 45 seconds, it seems as if you have some rather
severe overload on your links.
