This could be the problem where fragmented memory causes atomic higher order allocations to fail, for which there is a fix in -mm, which should make its way into 2.6.11.
Also, the increased atomic memory reserves in current 2.6-bk should alleviate the problem.
As a temporary workaround, you can increase /proc/sys/vm/min_free_kbytes
BTW. what does `free` say when the allocation failures are happening? - 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/
