We had a similar issue with our MySQL server farm (seven dedicated MySQL servers). Replication was very slow, falling behind for no apparent reason. We were reaching 24 hours of lag! We never had that kind of lag before. A couple of minutes at the most.
Long story short, we rebooted to 4.15.0.34 and the servers caught up replication with in minutes!
