    Subjectmemory leak in kernel NFS daemon w/ 2.2.10
    Our file server started to get slow after a two weeks and we noticed that
    all the memory is use and not by any programs.

    Here is a report from top (sorted by memory usage)
    All this machines does is run kernel nfsd.

    Its a dual pentium ii 400mhz w/ ultra 2 scsi drives
