Not sure about tracing per se, but if you can run the server program
without detaching from the console, the following two lines of code
can be exceptionally helpful:

 import pdb
 pdb.set_trace()

This lets you manually single-step through the code to find the source 
of the trouble (and other features, probably including some real 
tracing).
