The problem is that that buffer heads are only reclaimed when the pages in that memory zone are scanned. This does not help when you have 63GB of highmem and only 1GB of lowmem - low memory will be full long before the VM starts scanning high memory. The solution is to not use a 32 bit kernel with 64GB of RAM :) -- All rights reversed. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
