Yet another guy who thinks that Erlang developers reading this list are 
superheros with amazing powers that allow them to magically guess the 
version of Erlang/OTP he is using, the platform/OS, the details of his 
application and of WebSocket's code, the patches to e.g. mochiweb he has 
done, etc. and provide a verdict whether the problem he is experiencing 
could be related to an equally underspecified question somebody posted 
three months ago.

Sorry to disappoint you but the fact is that they are mere mortals. ;)

If you helped them a bit more by giving some more details and more 
importantly by posting some code that exhibited the problem you are 
experiencing, you chances of getting an answer would increase.
