    See here ? you have 'only' 880212 kB of LOWMEM, and 66 MB free.
    all kernel structures (you can see them in /proc/slabinfo) are lying on this
    zone, no matter you add RAM on your machine (more RAM end up in HighMEM zone,
    wich is basically unused on your setup)

    Since you have a 64bits CPU, your best move would be to use a 64bits kernel
    (you can keep all user land in 32bits mode)

    With a 64bits kernel, kernel land structures would not be constrained in a
    small area, but can use full RAM.

    I'm curious you have so many sockets but few entries in route cache...
    basically all connections come from few machines ?
