[chef] Can't connect to RabbitMQ after upgrade/downgrade debacle

[Luke Jolly < >]

I accidentally did a gem update on a working chef server box.  This broke chef.  After rolling back all the gems I believe where updated (chef and chef-server 0.10.4), I can now run chef, but it is erring.  It is failing to talk to rabbitmq correctly.  Rabbitmq is complaining about bad_headers.  Here's the errors I'm getting:

chef server.log

rabbit.log

Here's all my gem versions, and other package versions:

CentOS release 5.4 (Final)

rabbitmq-server.x86_64         1.7.2-1.el5

couchdb.x86_64                      0.11.2-2.el5

yum ruby versions

I did notice that there are some older versions of gems installed through yum, but I believe the new ones are indeed running.  I'm at my whit's end on this one and would love any help or suggestions.
