    Hi,

    in SM59 under TCP/IP check AI_DIRECTORY_JCOSERVER and AI_RUNTIME_JCOSERVER. May also check the application sap.com/com.sap.xi.services in the J2EE Engine.

    Other solution is reduce the number of parallel processes. see note 862405. and the last one is tuning the parameter CPIC_MAX_CONV

    Regards

    MArco.
