    The machine has 256Mb of RAM, 36Gb scsi drive and is a 1.3Ghz AMD cpu.

    I've switched MAXUSERS back to 0 now, right now before reboot my mbuf sysctl values read:

    # sysctl -a | grep mbuf
    kern.ipc.mbuf_wait: 32
    kern.ipc.nmbufs: 260000

    I'm stumped, stumped like a tree!

    James.
