(2006/06/01, updated 2006/08/28) An error in the statistics-keeping
logic in the UMA kernel memory allocator has led to the number of
requests for mbufs denied (as reported by netstat -m) to increase
erroneously. A fix for this problem has been committed to HEAD,
RELENG_6, and RELENG_6_1. More information is contained in errata notice
FreeBSD-EN-06:02.net.
