RMQ + Juno

Yeah, I know. 173 versions out of date. But we've got an old cloud kicking around and it's having some weird problems, and we're trying to eliminate things. One thing is RMQ -- we were wondering if anyone knows what would happen if we flushed all the queues; we'd kinda like to start that from a clean slate. Is that a Bad Idea(tm), or would stuff simply re-populate organically? Thanks! -Ken
