[rabbitmq-discuss] UNEXPECTED_FRAME - expected content header for class 60, got non content header frame instead

[xeon Mailinglist]

I am trying to run python multiprocessing to execute a remote function that 
I call with the help of celery. My program runs  ok if I just run one 
process. But when I run more than one process, I get the error below. Is it 
because of incompatible versions in python plugins and rabbitmq?

Process Process-1:
