The Question is:
What is the correct way to force an exit from a threaded application that will
not cause a bugcheck and the associated output. We have tried SYS$EXIT and
get the following:
%CMA-F-EXIT_THREAD, current thread has been requested to exit
%DECthreads bugcheck (version V3.15-267), terminating execution.
% Reason: lckHandoff: not owner; lock = 0x00000000000EC118, value =
0x0000000000000000, expected = 0x00000000004E3B40
% Running on OpenVMS V7.2-2 on AlphaServer 4100 5/533 4MB, -2048Mb; 4 CPUs
% The bugcheck occurred at 02-MAY-2002 15:20:52.82, running image

The Answer is :
This appears to either be a bug in DECthreads, or an application stack
corruption -- DECthreads is sensitive to stack corruptions, and this
DECthreads lckHandoff bugcheck can be one of the results of a stack
corruption. This could also potentially be a problem within DECthreads.
Assuming that you have current ECO kits applied, please contact the
customer support center. Details on the application and on the context
of the $exit call will likely be required. A program that can reproduce
the error can be useful, as well.
