Check if service is running?

[Andy Morsell]

After having the modified version running on my production server for several
days, I have discovered that my service lockups are not detected by this
script.  I did quite a bit more experimentation on my locked up server (I
can lock it up in a two step operation with the FDO raster provider) and
here is what I discovered when the service is in it's locked up state:

I can establish a site connection
I can create a session
I can create a resource service
I can create a feature service
I can create a mapping service

However, as soon as a I try to get a runtime map from an existing map
definition, it fails.  But, when it fails, it just stalls with no errors and
nothing is ever returned so a Try, Catch does not do anything.

For now, I'm back to restarting the service every couple of hours through a
scheduled task.
