Both SNFServer.exe and SNFClient.exe can be run in a debugging mode which
produces additional output. In order to run these programs in debug mode
you can rename them so that "debug" or "Debug" is in their name, or you
can call them in a sub directory so that the path to the program conains
"debug" or "Debug".

SNFDebugClient.exe --

The SNFClient.exe debug mode will display the entire XCI session for each
call. This is a good way to see how XCI is used if you want to explore
communicating with the SNFServer directly from your programs.

SNFDebugServer.exe --

The SNFServer.exe debug mode will display a thread status report each
second along with the usual running statistics line. The thread status
report will show all active theads, what they are doing (generally), and
whether they are running or have stopped. If a thread stops due to an
unhandeled exception then information about that exception will be
displayed in the status report.

There is a special version of the control script that will run the server
in debug mode and capture it's output in a file called debuglog.

20080325 -- At this time there are a few systems that are reporting an
intermittent bug where SNFServer will either stop answering requests or
it will stop reporting telemetry. When this happens there are no errors
reported in logs, no exceptions thrown, no corrupted programs, nothing
unusual at all --which is, of course, the most unusual thing of all. The
program continues to run -- it's just not listening (or talking).

On all but a handfull of systems SNFServer runs reliably for hundreds of
days at a time without stopping until told to do so... This includes our
lab computers... We hate mysteries -- the thread status report is designed
to help us learn something about this bug since we are not yet able to
reproduce it.

To run SNFServer in debug mode, create a copy of SNFServer.exe named
SNFDebugServer.exe and use the debugsnfctrl script to launch it (or you
can launch it your own way -- the goal is to capture stdout and errout to
a file called debuglog so that we can, hopefully, learn something).

If you are not experiencing the bug then please run SNFServer.exe in the
normal way.

Thanks
