Stopping the trap forwarder daemon
From MVS™:
P TRAPFWD
If TRAPFWD was started from a cataloged procedure, procname is the member name of that procedure. If TRAPFWD was started from the z/OS® shell, procname is useridX, where X is the sequence number set by the system. To determine the sequence number issue d omvs u=userid from the console. This will show the programs running under the user ID.
From UNIX:
kill < pid >
Issue the kill command to the process ID (PID) associated with TRAPFWD. To find the PID issue the ps -ef command from the z/OS shell.
