CherryPy cpstats and ws4py

[Israel Brewster]

Ok, let me ask a different question: the impression I have gotten when trying to find help with CherryPy in general and ws4py specifically is that these frameworks are not widely used or well supported. Is that a fair assessment, or do I just have issues that are outside the realm of experience for other users? If it is a fair assessment, should I be looking at a different product for my next project? I know there are a number of options, CherryPy was simply the first one suggested to me, and ws4py is what is listed in their docs as the framework to use for Web Sockets.

Thanks for any feedback that can be provided.

Maybe someone with more general python knowledge than me can figure out the traceback and from there a solution.

I am now trying to get a little more visibility into the functioning of the server, so to that end I enabled the cpstats tool by adding the following line to my '/' configuration:
