Hi Team,

I have message flow(sequence of nodes as below) which uses TCPIPClientOutput Node to send feed to splunk HeavyForwarder(TCPServer) via radware.

I see some intermittent BIP2114E error written in the IntegrationServer logs. My understanding about the error is due to concurrent usage of connection manager/pool while establishing connectivity to TCP server.

Can some shed some light in understanding the error in detail or am I missing some properties to be set on the TCPIP nodes which is causing the error..

Flow Overview : MQInput->JCN->TCPIPClientOutputNode(failure and Catch terminals of MQInput are connected to failure handler subflow).

IIB Version: 10.0.0.9

OS: zOs

Seems to be related to the fact that an arraylist is being modified in a non threadsafe manner... Is your java compute thread safe?

See https://github.com/eoinsha/JavaPhoenixChannels/issues/19

Have fun

Thanks for your reply. The linked shared by you has at least given me some idea about the exception.

JCN used in the flow doesn't have any array list and also the concurrentModitionException is due to HashTable.Enumerator() method used in the native code of TCPIP node.
