error proc size ...

[VP <vpedro.pias@xxxxxxx>]

I'm testing dragonfly src with freebsd-4.9 .The kernel (dragonfly)
compile fine and  i think its works OK,but when i want to stop the 
conection with my ISP i obtain a error

"killall ppp"

 error:
  proc size mismath(52448 total,1064 chunks)
  userland out off sync with kernel,recompile libkvm etc

 Any help is apreciated
