Cannot shut down the z/OS Log Forwarder by using the STOP command

The z/OS® Log Forwarder procedure cannot be shut down by using the STOP system command.

Symptom

In rare situations, you cannot shut down the z/OS Log Forwarder procedure by using the STOP system command (P GLAPROC).

Cause

The cause is an infrequent failure of the Java™ virtual machine that is used by the z/OS Log Forwarder to shut down.

Solution

Use the CANCEL system command (C GLAPROC) to cancel the z/OS Log Forwarder procedure.

Attention: When the z/OS Log Forwarder restarts after it is canceled in this manner, it might restart in cold start mode. In cold start mode, the z/OS Log Forwarder does not resume log data collection at the point where it previously ended. Therefore, the last log record that was previously processed might be missed.
