They are almost certainly hurting their total throughput. First, with the downtime of the reboot. Second, with the having to repopulate file system cache from disk. It is a fairly sure way to release space claimed by "ghost" files back to the file system and memory claimed by persistent shared memory pools back to RAM/swap, but both of those can often be handled without a reboot. -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
