Hi,

The part of the job included in the <finally> starting on line 1907 is:
<finally>
<if expr="MyProcessHandle != 0">
<sequence>
<log message="True">
" Interaction '%s': Signal '%s' sent due to User Abort" % \
(Interaction['Name'], Interaction['AbortSignal']) </log>
<log message="True">
" Waiting for signalled interaction to exit"</log>
<script>
while True :
msg = EMACHTools.STAFsubmit2('LOCAL', 'PROCESS', \
'FREE HANDLE %s' % MyProcessHandle)
if msg == None :
break
RC = msg.split("RC=")[1]
RC = int(RC.split(",")[0])
if RC == 5 : # RC 5 is 'Handle does not exist'
break
if RC != 12 : # RC 12 is 'Process Not Complete'
FatalMsg = msg
break
time.sleep(0.1)
</script>
<call function="'EMACH_CheckError'"/>
<log message="True">
" Signalled interaction is gone"</log>
</sequence>
</if>
</finally>
The code is here to wait for a process termination after user has terminated a
block.
I looked for the process the loop wait for, found it to be done and having a
RC. So I
released the handle via staf, but that didn't make the job run.

Thinking about the call trace: why do I see <finally> as the innermost element?
I would guess
the job is looping in <script>, but shouldn't <if> be the innermost then? When
looking for
the jvm (ps command) I see its CPU-usage count as fast as real time.
Any help to find the problem is welcome.
Best Regards
Bodo
