[rabbitmq-discuss] clearing a queue error

[Warren Smith]

I believe this error started when the servers were at version 3.1.1. I also upgraded today to 3.1.5, to confuse things more.

I'll send you the mnesia directory.

Yep, I'm ok with losing the queue and the data. I'd just prefer not to lose the rest of the configuration.

Thanks,


Warren
