VTAM® issues this message when subtask abnormally terminated more than four times in the last 30 minutes. VTAM tried to reattach it by using the ETXR exit routine but could not because the abend threshold for the subtask was exceeded.
VTAM will make no further attempts to attach the subtask. VTAM continues without the support of the subtask.
Save the system log for problem determination. It might be necessary to halt VTAM and start it again if you need this subtask.
Examine the output from the operator to determine the cause of the problem. See the z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures for information on the abend procedure.
