    Hello All,

           I have in my work one vpn server (point to multi-point ) using
    MPD, AAA with FreeRadius and 5.3-STABLE, sometimes a look in dmesg this
    messages.

    "ng_mppc_decompress: too many (4095) packets dropped, disabling node
    0xc34d4800!ng_mppc_decompress: too many (4004) packets dropped,
    disabling node 0xc33be700! "

          What is the problem? i using a generic kernel with a "HZ=2000 e
    POLLING"

    dmesg output
