    I found the mbuf leak.  It was introduced in a commit I made in April
    which allowed control and address data to be thrown away on insufficient
    socket buffer space.  The wrong error code was being returned and
    preventing the mbuf from being freed.

    The mbuf leak occurs most often when a large amount of information is
    sent to syslog, such as by a mail or web server subsystem.

    This bug is pretty serious and will require 1.10.1 to be rolled this
    weekend.  The 1.10 slip tag has already been updated so release
    users can get the change now from the main site (or tomorrow from the
    mirrors).  HEAD's slip tag has not yet been updated because of some
    issues in HEAD at the moment.

    The commits to HEAD are:


    The commits to RELEASE are:
