A few warnings i cant track down

[mrossFTEK]

im getting these two warnings in my log.. (running latest version of cacti)
I have been trying to track down the cause, and I'm not able to figure it out.
im sure its something super simple to fix\change, but I thought i'd ask the experts here.. any insights to point me in the right direction?
