The z/OS® Log Forwarder procedure cannot be shut down by using the STOP system command.
In rare situations, you cannot shut down the z/OS Log Forwarder procedure by using the STOP system command (P GLAPROC).
The cause is an infrequent failure of the Java™ virtual machine that is used by the z/OS Log Forwarder to shut down.
Use the CANCEL system command (C GLAPROC) to cancel the z/OS Log Forwarder procedure.
