I now personally have thought that this problem is the kernel not keeping track of reads vs writers properly or not providing enough time to reading processes as writing ones which look like they are blocking the system.... If you want to do a simple test do an unlimited dd (or two dd's of a limited size, say 10gb) and a find / Tell me how it goes :) ( the system will stall) (obviously stop the dd after some time :) ). http://article.gmane.org/gmane.linux.kernel.device-mapper.dm-crypt/4561 iirc can reproduce this on plain ext3. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
