    Subjectknfs OOPS on kill (2.2.14pre16)

    I just compiled 2.2.14pre16 and then manually loaded knfs:

    # rpc.mountd
    # rpc.knfsd

    Except that I meant to run more than one, so I killed the sole nfsd and
    got this: (snagged from messages)

    Looks like only the last trace address was decodable by klogd??

    Anyway, mountd died at the same time, so I restarted it.
    But then rpc.knfsd 8 kept dying with "address already in use" although
    no nfsd's were showing with ps.

    After reboot, and retrying without forgetting the '8' all seems OK.

    If anyone needs, I can attempt to repeat this.

    grep -i nfs /usr/src/linux/.config

    # CONFIG_NFSD_SUN is not set

    Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs
    gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)

    rpc.mountd/rpc.nfsd as distributed with RH 6.0.
    More details on request.
