Bug Description

Sam Morrison (sorrison) wrote 37 minutes ago (on bug 832507):

We recently had a console log grow to 5.5GB

When a user tries to get the console via the API it in turn packs this into a message and sends it off to rabbitmq.
For us this completely killed our rabbitmq cluster. The user kept trying to get the console knocking out a rabbitmq server each time (each rabbit has 4GB of ram)

To me this seems like nova could do something here like not try and send a 5.5GB message through rabbit?
