    Subject2.2.11: unkillable, perpetually-sleeping rpciod
    From
    Date
    Greetings!  The kernel has all of the patches listed on Alan Cox's
    errata page for 2.2.11. When running autofs, and having an NFS mount
    expire, the autofs daemon is unable to umount the corresponding
    directory because of this stuck rpciod process. Here's what I have:
