[ https://issues.jboss.org/browse/JGRP-2237?page=com.atlassian.jira.plugin.... ] kfir avraham commented on JGRP-2237: ------------------------------------ i attached logs from server_A, server_B, and conf file. in this case (after upgrade to version 4.0.8) it is look better but from some reason after a few restarts, server_A doesn't sent a join message to the other machine, and create new view with 'is_coord-true'. any idea what could be the reason for that? BTW, we must to use in ' port_range="0" ', because we want to use only in this port, and it worked perfect in 3.6.11 version (we upgraded the version because security issue). when i set ' port_range="5" ', they not discovered each other from the beginning. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
