RRDcached Error on Central poller

Greetings!

I have this error message on the rrdcached status on my central server and I am not sure what is causing it. The graphs seems to be fine but the poll time for the pollers are ridiculously high. Any thoughts on where I can tweak so that this error is out of the way? I feel this may have a major hand in contributing to the poll times:
