Florin POP commented on JCS-244:
--------------------------------
I have clear steps for reproduction now also outside WebLogic context.
Have a distributed cache on 2 nodes for example. Configure in the cache.ccf
files that the listener port is 7800 for both nodes.
Start the 2 JVMs and in the beginning both are communicating, the
*JCS-LateralTCPListener* can be seen up on both nodes.
In order to break one of the nodes and make the listener disappear, I did a
telnet host2 7800 and just closed the session without sending anything.
At this moment I can se on the JVM from node 2 the exception:
java.nio.BufferUnderflowException
at java.base/java.nio.Buffer.nextGetIndex(Buffer.java:721)

at java.base/java.lang.Thread.run(Thread.java:1583)
and the *JCS-LateralTCPListener* thread is no longer alive, thus the caches can
no longer communicate.
> JCS-LateralTCPListener dies and not automatically recovers

> Project: Commons JCS
> Issue Type: Bug
> Components: TCP Lateral Cache
> Affects Versions: jcs-3.2.1
> Reporter: Florin POP
> Priority: Major
>
> We are using LateralTCPListener in Weblogic context in OIG14c, at one point
> the listener thread is dying and from that point on the other nodes in the
> cluster are no longer able to communicate with this node. One by one all
> nodes in the cluster happen this.

> *Description*
> *-----------*
> *Thread 361(JCS-LateralTCPListener-aps-oim4-prod.eu.novartis.net:7800) exited
