[Condor-devel] What is the starter trying to do at line 321 in NTsenders.C?

["Ian Chesal" <ICHESAL@xxxxxxxxxx>]

Debugging a persistent problem we're having in our SJ system where our
Windows machines end up Claimed+Idle after a short period of time.
Windows machines are failing to run jobs and I'm seeing in the
StarterLog file:

These assert errors in NTsenders.C and NTrecievers.C keep popping up.
Now that I've got the source for 6.8.0 I'm looking at NTsenders.C. The
REMOTE_CONDOR_begin_execution is where this assert exists. Right before
the assert is:

	syscall_sock->decode();
	result = syscall_sock->code(rval);
	ASSERT( result );

Is this a socket call to shadow or to something else? I'm having trouble
determining where the socket was being opened to.

P.S. I can take this to the condor-user lists if you guys want. I just
figured I was quoting lines of code so it'd be better off on this list.
Let me know...
