:OK, it's happened again.  I was doing a make on a partition with softupdates
:and swapping vtys.

    EEek.

:apart from that, all are sleeping on the obvious things: select, ttyin, 
:wait, pause, etc.

    You have an MFS partition?   Maybe you'd better describe the full machine
    configuration.  Memory, disks, swap configuration, and so forth.

    It looks to me like it's running out of memory, but it is very odd to
    see the pagedaemon and syncer both in a run state.  I don't think it
    is softupdates per say, but softupdates could be exasperating some
    other problem.

    Just for the hell of it, try reducing debug.max_softdeps with a sysctl
    to something relatively small, like 100 or 200.
