Hi Brandon,

I'd guess this is related to the EPOLL support that is used to efficiently get 
notified when something on the file descriptor arrives, so basically its 
necessary for TCP support.

This is really strange, i really could not imagine how an AVP operation like 
this could be related to the TCP core infrastructure. Do you notice some other 
(earlier) errors in the logs? Perhaps its just something that its generated 
because its stop from an earlier error?
