Error description

  • If an IMS Connect PORT task abends and BPE abended the other
    PORT tasks, a loop in FUNTDB01 may occur. This is because BPE
    abended a PORT task while a latch was held by FUNTDB01. The
    Abend prevented the latch from being released by the task.
    This caused a CEX non-PORT task to loop trying to obtain the
    latch left by the abending PORT task.

    mulitple ports defined, a loop in module FUNTDB01 can
    occur. The loop is a spin lock loop trying to obtain
    a buffer latch held by the abending Port task.

    make sure that the buffer latch can be released for
    the abending Port task.
