Both SNFServer and SNFClient 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 --

The SNFClient 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 --

The SNFServer 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.

The snf-server control script can be used to run the server in debug
mode and capture it's output in a file called debug.log (in directory
/var/log/snf-server by default).  Please see the Debugging section of
INSTALL in the top-level directory of the distribution for the
procedure and further details.

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, use the procedure in the INSTALL file
(or you can launch it your own way -- the goal is to capture stdout
and errout to a file called debug.log so that we can, hopefully, learn
something).

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

Thanks
