I am using version 5.5.0 and after connecting 1000 clients with nio transport
connector, clients start to disconnect with the exception:
15:24:11,307 WARN FailoverTransport:231 - Transport (null) failed to
nio://server2:61618 , attempting to automatically reconnect due to:
org.apache.activemq.transport.InactivityIOException: Channel was inactive
for too (>30000) long: server2/192.168.5.192:61618 [{InactivityMonitor Async
Task: java.util.concurrent.ThreadPoolExecutor$Worker@2083fc73}]
And in the server I am getting these INFO messages:
17:14:46.808 [ActiveMQ NIO Worker] INFO o.a.a.broker.TransportConnection -
The connection to 'null' is taking a long time to shutdown.
after querying a heap dump using Eclipse Memory Analyzer.

I seems that although I am using nio each connection is consuming a lot of
memory.
How can I reduce memory consumption ?
