Big memory leak - 3725 and 12.3

    Hi there

    Was wondering if anybody can try and repro this. If I enable IDS (ip audit)
    policy on my outside NIC of my edge router (a 3725) running 12.3(3) I get a
    big memory leak.

    Now if I monitor memory usage via SNMP I get a constant erosion of available
    process memory. It seems that irrespective of how much actual load is on the
    box, the rate of loss is constant, and a 4 day view on the graph shows a
    very steady drop at a pretty much constant rate of decay.

    Eventually routing stops and you have to reload. With 128MB of RAM, it will
    take around 6 days to kill it.

    If I turn off ip audit, the leak stops, but no memory is reclaimed.

    For what its worth, this router runs ipsec cryptos, nbar, cbac, radius auth,
    overloaded nat, etc.
