Weird message in dmesg

[OriS]

Hello all,

I have a strange warning message in dmesg:

    warning: total configured swap (15728640 pages) exceeds maximum
recommended amount (22369984 pages).
    warning: increase kern.maxswzone or reduce amount of swap.

(The configured pages are actually less than maximum)

The value of kern.maxswzone in /boot/loader.conf is:

    kern.maxswzone=201326592

Anyone knows what's going on?!
