Hi all.

I prefer to build all ports in /tmp, which is actually a tmpfs 
filesystem. I have 8G partition. But when I tried to compile Apache 
OpenOffice system starts shooting processes when I was near 6G of swap.

Oct 11 18:12:32 ar1l0u kernel: swap zone exhausted, increase kern.maxswzone
Oct 11 18:12:32 ar1l0u kernel: pid 1334 (java), uid 818, was killed: out 
of swap space
Oct 11 18:12:32 ar1l0u kernel: pid 74518 (thunderbird), uid 1001, was 
killed: out of swap space
Oct 11 18:12:32 ar1l0u kernel: swap zone ok

As I'm running rather current version I see r240097 in the log that 
states that there is no maxswzone setting for amd64 anymore. When I 
tried to query this parameter I got:

 > sysctl kern.maxswzone
kern.maxswzone: 0

What was that? Did that mean that 6G is a maximum swap size now?

PS: I'm retrying now with kern.maxswzone set to 256M.
