Items held entity error?

Not sure if this is /kits or not.    The error is "Item's Held Entity not removed!F1 Grenade -> grenade.f1.entity[1166963769]"   The number at the end changes with each iteration of the error, and it's happening fairly constantly.  
Not sure what to do about this, but it's dragging our performance  down substantially.

really hoping for some help and/or an update (if it is kits causing it)
