dummynet warnings

[Sergey Yaroshevskiy]

Hello

I've got some warnings from my freebsd 9 box:

...
Apr 23 12:06:10 pipe kernel: copy_obj   (WARN) type 4 inst 65612 have 92 need 96

Apr 23 12:06:10 pipe kernel: copy_obj   (WARN) type 4 inst 65615 have 92 need 96

This box is configured as bridge and it's mine function is piping users.
Googling sent me to source of netinet/ipfw/ip_dummynet.c (lines 800-802)
http://www.leidinger.net/FreeBSD/dox/netinet/html/dc/d3a/ip__dummynet_8c_source.html
but i did not understand how to fix this problem
