A question arises. The value 256 (1G KVA space) acts as a default for any system installation, not depending of real phisical memory size. So for any server with RAM less than 2G (which is a majority I presume) the KVA space occupies more than half of physical memory. It can even be more than TOTAL phisical memory for servers with RAM less than 1G. Isn't it bad for a system? It seems that it is not. Then why cannot the KVA space always be made as some big value? If it is important for servers with large RAM, why it is not or a smaller servers? Can anybody besides Terry which seems to be unavailable now help?
