Comment 33 for bug 855030

Hey,

Are you using eventlet with both kombu and carrot?

The difference then would be that Kombu synchronized *_declare calls by delegating them to another greenthread
and having the current thread wait for that thread to finish (kombu.syn.blocking)
So in a sense it *should* be safer than carrot, why it wouldn't be I'm not sure.
Also are you declaring entities both when publishing the request *and* when publishing the reply?
