I posted this to the CherryPy and ws4py mailing lists, but in the week since I did that I've only gotten two or three views on each list, and no responses, so as a last-ditch effort I thought I'd post here. Maybe someone with more general python knowledge than me can figure out the traceback and from there a solution.

Is it possible to use ws4py in conjunction with the cpstats CherryPy tool? I have a CherryPy (3.8.0) web app that uses web sockets via ws4py. Tested and working. 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:

tools.cpstats.on=True

Unfortunately, as soon as I do that, attempts to connect a web socket start failing with the following traceback:

Disable tools.cpstats.on, and the sockets start working again. Is there some way I can fix this so I can use sockets as well as gather stats from my application? Thanks.
