Re: network01.patch - MPSAFE network interrupt

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

    The mbuf cluster stats are clearly a bug in the statistics, but
    the mbuf current/peak/max (current part) might not be and that
    could indicate a leak.

    Could you generate a kernel core with the mbuf susystem
    in this state and throw it onto leaf ?
