This can happen because of networking problems. TCP would help you
with its flow control. Can you give us details about why the channels
with TCP did not work?
My config on both servers is using VLANs :

I tried to force the conf to use vlan 24 :
<channel name="TCP SEQ Channel" template="tcp_sequencer" initialized="yes">
<memorymanagement size="40000000" up_threshold="15000000"
down_threshold="7000000" />
<chsession name="hederalayer">
<parameter name="gossip_address">224.1.1.5</parameter>
<parameter
name="local_address">192.168.0.27:12000</parameter>
</chsession>
</channel>
And both servers try to run on vlan 10 :

I don't want to use vlan 10 because it's a special closed network
running with dhcp addresses that are not suitable for that purpose. In
fact, even if I don't force the IP address in the TCP config,
controllers never see each other.
Also note the 1496 MTU on interfaces that could perhaps be the cause of
some trouble ...

Sylvain.
