Description of problem:

It appears that the consumer can get in to a condition in which it is not possible to install errata without restarting goferd (on the client).

The scenario below is one example where this has been observed; however, it may occur in other situations as well.  Based on discussion with Jeff, this might be related to the repos changing within the redhat.repo; however, that is being investigated.

Version-Release number of selected component (if applicable):
pulp-server-2.1.1-0.9.beta.el6.noarch

How reproducible:
always

Steps to Reproduce:
1. sync a rhel repo (e.g. rhel6)
2. follow the steps outlined in bug 958932 (involving the zoo repo)

3. unregister the client, e.g.
subscription-manager unregister

4. clean the client, e.g.
subscription-manager clean

3. register client, e.g.
subscription-manager register --org ACME_Corporation --environment dev/rhel6_view_2

3. subscribe client, e.g.
subscription-manager subscribe --pool 8a8d01353e56ebfd013e5774d099004a

4. update the redhat.repo, e.g.
yum repolist

6. attempt to install an errata

Actual results:

Packages not updated on the client.  The following errors observed in the client's agent.log:

Expected results:
No errors in log and packages updated on the client.

Additional info:
Note: if goferd is restarted on the client, the errata can be installed from the server.
