Hi,
I see that you use both ipv4 and ipv6 stacks, I think it can somehow affect
this behavior, so, I would recommend enabling -Djava.net.preferIPv4Stack=true
for all nodes in the cluster(including clients). Also, why do you decided
to set such parameters to the communicationSPI:
<property name="messageQueueLimit" value="3000"/>
<property name="socketWriteTimeout" value="6000"/>
<property name="socketSendBuffer" value="65536"/>
If after suggested change you will still witness this problem, please
provide full logs from all nodes in cluster.
