You are assuming that the situation actually occurs. In real life, it will not occur unless the critical server is running away with memory. I have never, ever run one of BEST's servers out of swap. It has never been an issue. And, I can only repeat, again, that long before a reasonably configured FreeBSD system runs out of swap it would become unusable from the I/O overload. And you also haven't bothered to address my other point: In order to configure a system that guarentees backing store, you need to configure that system with 8x or more swap then you would a normal system. If you think there was a chance of a normal system running out of swap, what do you think would happen if you configured a normal system with 8x swap? -Matt Matthew Dillon <dil...@backplane.com> To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
