    *                      X'061D' and task getting hung when      *
    *                      CICS process CTG request over IPIC.     *

    * RECOMMENDATION:                                              *
    ****************************************************************
    A ECI request comes from CTG over IPIC, the task CPMI attached
    but get queued on TCLASS, CTG will send a EXPD with purge type
    TIMEOUT to CICS after the ECI request TIMEOUT expires. DFHISRR
    calls DFHISEM.PURGE_CONVERSATION and ABEND_CONVERSATION to
    resume CPMI for ABEND process. Neither dfhisxm.release_xm_client
    nor dfhisis_send_error free receive ISSB because DFHISEM
    ABEND_CONVERSATION set issb_timeout_rcvd and issb_purged to
    true. When more and more ECI requests time out, all the RECEIVE
    sessions will being held by tasks and DFHISRR will report
    exception NO_ISSB_AVAILABLE which leads to DFHIS1023
    conversation error (code X'061D') report and task hung.
    

Problem conclusion

  • DFHISXM routine release_xm_client has been changed to free the
    issb if issb_timeout_rcvd is set to true.
