    Just curious, but how long would it take a system with 8GB RAM, using 4G
    or 64G kernel to fall over? One thing I've noticed, is that 2.4.19aa2
    runs great on a box with 8GB when I don't allocate all that much, but
    seems to run into issues after a large DB has been running on it for
    several days. (i.e. the system get's generally a little slower, less
    responsive, and in some cases crashes after 7 days).

    Yes, I know, sounds like a memory leak in something, but aside from
    patching Oracle from 8.1.7.4(dba's can't find any new patches ATM), I've
    tried everything except changing my kernel.

    Could this be similar behaviour?
