kfir avraham commented on JGRP-2237:
------------------------------------

i changed 'VERIFY_SUSPECT' timeout to 500 (as in your configuration), and i got the same issue (see log below).
when i changed 'port_range', they not discovered each other from the first time. 

*it is happened also after shutdown for a few minutes, and not just for restart.
