Broken pipe socket exception occurred when implementing the tcp connection pool

[yogya]

I had implemented a connection pool for TCP connections using CachingClientConnectionFactory class in Spring 2.2.0 release.


This is the configurations that I used.

<int-ip:tcp-connection-factory id="tcpConnectionFactory"
		deserializer="deserializer" type="client" host="${socket.host}"
		port="${socket.port}" so-keep-alive="true"/>

	<int-ip:tcp-outbound-gateway id="outboundGateway"
		request-channel="sendStringMessageChannel" reply-channel="recieveStringMessageChannel"
		connection-factory="tcpConnectionPool" request-timeout="10000"
		reply-timeout="10000" />

	<bean id="tcpConnectionPool"
		class="org.springframework.integration.ip.tcp.connection.CachingClientConnectionFactory">
		<constructor-arg ref="tcpConnectionFactory" />
		<constructor-arg type="int"
			value="50" />
	</bean>

	<bean id="deserializer"
		class="com.infrastructure.connection.SocketInputStreamDeserializer" />

But I am experiencing an issue when using the app after a long idle time.

Thanks in advance for any guidance related to this.

Please don't post the same question twice; I answered on the other thread.
