Hello

I am running -current (Feb 2 2002) i386, my kernel was
compiled with the "altq most common options". After to run
/etc/rc.d/altqd start, I got a lot of error messages:

altq_etherclassify: headers span multiple mbufs: 14 < 34
altq_etherclassify: headers span multiple mbufs: 14 < 34
altq_etherclassify: headers span multiple mbufs: 14 < 34

I have compiled the kernel again with NMBCLUSTERS=4096
and "make USETOOLS=no depend all", but when I reboot the
machine and start altqd, the same messages appears,
exactly with the numbers 14 and 34 (a lot of times).

My reason of use ALTQ is for limit the bandwidth of the
service 1214/tcp (kazaa, morpheus, audiogalaxy)

This is my network diagram

Does somebody can tell me some hints?
