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?
