	System      : OpenBSD 2.6

>Description:
	kernel configured w/ ipv6 demonstrates mbuf/memory leaks on heavy
	udp traffic. same kernel from the same sources exculding ipv6 from
	the config does not expose any behaviour of a kind mentioned.
	these particular and unfortunate errors started to appear
	approximately in the early 20ths of december.
>How-To-Repeat:
	have a kernel compiled w/ ipv6.
	put substantial udp traffic on an ethernet iface.
	observe "data modified on free list" errors.
	at least true w/ tftp and nfs traffic between two different
	endianess machines.
>Fix:
	dunno.
