You have a kernel memory leak.

It was a GFP_KERNEL allocation.

There's a grand total of 1.2MB of ZONE_NORMAL memory on the LRU. The rest (900MB-odd) is lost.

and it's not in slab.

Boy, 2.6.13 was a long time ago - I'm sure we fixed many leaks since then, but I do not recall any particular patch which might fix this, sorry.
Your best option would be to seek a kernel upgrade. - 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/
