It sounds as if you don't have enough physical memory for the task at hand. If that is the case, no amount of tweaking parameters will solve your problem; you'll just have to install more memory. You don't mention which application you're using or what type of processing is being performed. Depending upon the task, processing a file may require memory far in excess of the size of the file. -- Glynn Clements <glynn@xxxxxxxxxxxxxxxxxx> - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
