Carl, looking at the boundary chart it looks like you have periods of no
traffic also... prior to the spikes.

I also noticed you are using AWS from your logs, what instance types are
you using?  Do you have any network checks in place?

The logs show underReplication=true which leads towards what Joel was
theorizing as the issue.

Do you track stats on the cluster?
http://kafka.apache.org/documentation.html#monitoring I would expect
correlation of changes in the kafka stats and the boundary chart.
