[rabbitmq-discuss] RabbitMQ join_cluster error

Tue Mar 25 18:08:12 GMT 2014

That looks like the nodes of the cluster are running different Erlang 
versions. They should all be on the same version.

That said, I thought we'd converted that to a more intelligible error 
message (it could hardly be less). Which version of RabbitMQ are you 
running?

Cheers, Simon
