virtual memory management

[Zbigniew Szalbot]

Dear all,

Is there a FBSD command to manage virtual memory? I think my swap size is
now a bit too much used:

last pid: 19824;  load averages:  0.06,  0.05,  0.02   up 50+10:00:17 
08:54:00
230 processes: 1 running, 227 sleeping, 2 zombie
CPU states:  0.0% user,  0.0% nice,  0.4% system,  0.8% interrupt, 98.8% idle
Mem: 232M Active, 27M Inact, 91M Wired, 212K Cache, 60M Buf, 142M Free
Swap: 512M Total, 482M Used, 29M Free, 94% Inuse

The swap size usage grow so big probably because I started wget to
download an iso image and then WinSCP to grab it from the FBSD machine to
my laptop. When I started wget, the swap usage was around 19% and had been
like that for many days.

Is there any way to handle swap size usage other than restarting the box?

Thank you very much in advance!
