Although I've had problems with leaving Mozilla up for long times and it leaking. Without Mozilla running and running lots of other apps, I have almost 100% memory used, but 0% swap. If the swap starts to increase slowly over time, you _do_ have a leak somewhere. Probably not in the kernel (kernel memory never goes into swap). But if you want to see if the kernel is leaking, examine /proc/slabinfo once in a while and if you see something there constantly growing, then that might indicate a leak. Just pay attention to the first column. -- Steve - 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/ | |||||||||
