    Is this phenomenon specific to me?

    No, it isn't:

    term% ps|grep Broken
    none 917 2:08 42:50 264K Broken smtpd

    impressive!

    i don't see this problem, but i have implemented
    some fairly agressive spam control. perhaps this
    shows up after i tend to hang up.

    (it is possible to use nupas smtpd with regular old
    upas.)

    would anyone mind sending me a full backtrace?
