I'm still looking for a help in investigating this issue. The problem appears on
two 7.4 boxes, while 7.3 are working OK. Ktrace shows, that indeed some of
sendto() calls on netgraph control socket are failing with EPERM:
1246 mpd5 CALL sendto(0x5,0x2886e020,0x98,0,0xbf7fc9b2,0x5)
1246 mpd5 RET sendto -1 errno 1 Operation not permitted
but few seconds later, sendto() called on the same socket succeeds:
1246 mpd5 CALL sendto(0x5,0x286487c0,0x38,0,0xbf9feae2,0x6)
1246 mpd5 GIO fd 5 wrote 56 bytes

I looked at the netgraph code and I couldn't find any place where it returns EPERM.
