  • Closed as program error.

Error description

  • When a stale connection becomes present in the response
    connection pool and the IMS Callout Handler tries to send a
    response message with that connection, this will lead to an
    expected EOFException error being logged. However, this might
    then end up going into a loop causing an error message similar
    to the one below to be logged multiple times and for same
    correlation token.
    
    [0x8c800015][ims][error] source-ims-callout(IMS_Callout_FSH):
    Fail to deliver response (length: 1748, correlation token
    0x0028000XXXXXXXXXXXXXXXXXXXXXXX). Error:
    com.ibm.ims.connect.ImsConnectCommunicationException: HWS0008E:
    Failed to send or receive messages to and from IMS Connect
    hostName [10.XX.XX.XX], portNumber [9999]. Original error:
    [EOFException].
    
    This issue can prevent subsequent response messages from being
    delivered by the affected IMS Callout Handler.
    

Local fix

Problem summary

  • Customer who uses IMS Callout front protocol handler might see
    the HWS0008E error with the same correlation token repeatedly
    logged, if the IMS Callout front protocol handler failed to send
     or receive messages.
    

Problem conclusion

Temporary fix
