Log file fills up with error: "incoming chunk is broken" after about 24 hours of heavy traffic using 2.2.1 on linux

using the latest td-agent in production. After the agent gets about 24 hours old, it starts complaining and logging in /var/log/td-agent/td-agent.log "incoming chunk is broken". td-agent took up 100% CPU and fills up the disk with these log messages very quickly (about 5G/hr of these log messages with our setup). Had to take td-agent out of production due to this issue as this was unacceptable behavior and affected our production performance. This was on the app-server side and our td-agent configuration is here: http://pastebin.com/gEwKUPX1 We're basically just tailing nginx logs and allowing the app to send rails logs directly to the td-agent socket with failover servers downstream.
