Hi Team,
I am getting below error while implementing HA over ssl enabled acceptors in
both master and slave.
Error Master:

for more details.
This keep on repeating like anything in logs making CPU and JVM heap to go
high!
{{ERROR [org.apache.activemq.artemis.core.server] AMQ224088: *Timeout (10

has occurred.}}

{{Master is not able to communicate to slave over ssl causing time out issue
where sslv2 protocol is being shared by slave which is not accepted by master.}}
1.Could you please help on why slave is sending sslv2 protocol is the same has
been deprecated by oracle JVM in JDK 7 onwards and we are using JDK 8 ?
2.When client connects(external) to broker then TLS protocol is provided in
transport settings from their side, then why for internal communication where
master and slave or cluster brokers have to share information SSLV2 is used
(which is again blocked by JVM installed saying unsecure protocol) - This is
strange where internal communication in a product is blocked while external is
working :)
-------------------------------------------------------------------------------
my broker xml' are attached below:
Any help will be much appreciated![^master_broker][^slave_broker]
