PK70417: FUNTDB01 PRECEEDED BY AN ABEND IN A PORT TASK

Obtain the fix for this APAR.

APAR status

• Closed as program error.

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.
  

Problem conclusion

• The emergency termination process has been changed to
  make sure that the buffer latch can be released for
  the abending Port task.
