InactivityMonitor=false not working ?

Dear all,

In a network-of-brokers with 2 MQ instances (both ActiveMQ 5.9), I've configured 'ssl://0.0.0.0:61616?transport.useInactivityMonitor=false&...' on both machines.

The connection is set up from host xxxmlog3 with

<networkConnector name="BrokerLinktoXxxmlog4" userName="system" password="${activemq.password}" uri="static:(ssl://xxxmlog4:61616)?useJmx=true" duplex="true">

However - numerous messages about shutting down due to a remote error (alternating with establishing the connection):

2014-01-27 23:13:54,412 | WARN | Network connection between vm://localhost#3396 and ssl://xxxmlog4/192.168.251.116:61616 shutdown due to a remote error: org.apache.activemq.transport.InactivityIOException: Channel was inactive for too (>30000) long: tcp://192.168.251.116:61616 | org.apache.activemq.network.DemandForwardingBridgeSupport | ActiveMQ InactivityMonitor Worker

Apparently, 'useInactivityMonitor=false' doesn't seem to have any effect. Tried adding 'wireFormat.maxInactivityDuration=0' to the networkconnector, but same behaviour: not working.

Thanks,
Geurt
