Rod Widdowson commented on DAEMON-348:
--------------------------------------

> So are you saying that the code should remove the JvmSs entry if the 
> ThreadStackSize (TSS) field is emptied?

Absolutely.  I brought my customer's machine back to life by doing just that.

> I assume it does not create the entry if the TSS field is empty on initial 
> creation.
Correct.  It only gets populated when you change it.

> I don't have a Windows system handy at present to check
I have _loads_ of windows VMs lieing about if you need me to run tests.

> Just diagnosed an issue with a customer in which the java [process was 
> unrunnable).  This was because 
> {{HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Procrun 
> 2.0\shibd_idp\Parameters\Java\JvmSs}} was zero, (where {{shibd_idp}} is the 
> service.
> I managed to reproduce this behavior by
> * starting shibd_idpw (a.k.a prunmgr.exe)
> * modifying Thread Stack Size to be something
> * (verify with regedit)
> * clear the Thread Stack Size field
> * JvmSs is now zero
