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? --The GrandMaster - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
