Explanation: During VTAM® HALT QUICK, VTAM HALT, VTAM HALT CANCEL, or VTAM abnormal termination processing, VTAM found that no storage was available to schedule a TPEND exit for an access method control block (ACB) opened by a user application program or VTAM subtask.
This abend code is also issued during VTAM HALT CANCEL or VTAM abnormal termination processing if a TPEND exit for an ACB does not exist, the ACB was not valid, or the ACB storage was freed.
System action: The user application is abnormally terminated.
