[jboss-jira] [JBoss JIRA] (JGRP-2387) Message from a non-member causes FD_ALL to continually suspect it

[Bela Ban (Jira)]

Bela Ban resolved JGRP-2387.
----------------------------
    Resolution: Done


I changed FD_ALL and FD_ALL2 to drop suspicions of non-members: this way, no messages will be sent to non-existant members (e.g. by VERIFY_SUSPECT).

However, this won't fix the issue of messages being sent to non-members: if a message is sent to a non-member, the warnings will repeat until {{conn_expiry_timeout}} / {{conn_close_timeout}} in UNICAST3 will close the connection to the non-member.

> If an FD_ALL control message from a non-member is seen by FD_ALL, it will start continually suspecting that node. If msg_counts_as_heartbeat=true then any message from a non-member triggers the issue. The issue is cleared on the next view change.
> This does not cause any functional issues in the cluster, but can cause repeated WARN logs in some cases.
