PI79561: ADD A TIMER TO ABEND SERVANT AT SHUTDOWN IF THERE ARE STALLED THREADS

Fixes are available

APAR status

Closed as program error.

Error description

When using a setup like this:
BBOM0001I protocol_https_timeout_output_recovery: NOT SET,
DEFAULT=SERVANT.
BBOM0001I server_region_stalled_thread_threshold_percent: 25.

And a thread times out, but the servant isn't abended (due to
server_region_stalled_thread_threshold_percent not being
reached) and is still running when the sever is shut down, this
can cause the servant to not shut down.  A property needs to be
added to set a timer that will abend the servant is there are
stalled threads that have timed out that are still running when
the server is shut down.

Local fix

cancel the server if it doesn't shut down

* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V8.5 and V9.0 for z/OS               *

* PROBLEM DESCRIPTION: WebSphere Application Server for        *
*                      z/OS controller does not stop when      *
*                      requested.                              *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When using server_region_stalled_thread_threshold_percent a
server does not stop when requested because there are still
hung threads in a servant. A server will not stop until
all servants come down.

Problem conclusion

Updated the stop code to abend servants with hung threads when
control_region_on_stop_abterm_hung_sr_waittime is set
to a value greater than 0.
When control_region_on_stop_abterm_hung_sr_waittime is set to
the default of 0 servants with hung threads will not be abended.
When control_region_on_stop_abterm_hung_sr_waittime is set to
a value other than 0, the controller will wait that many
seconds before looking to see if there are servants with
hung threads that need to be abended. The abend code used will
be EC3 with reason code 042B0001.
