Yes. I try to modeling "out of swap" in FreeBSD-3.2-RELEASE.

I am sure, that setting limits in "/etc/login.conf" is not good decision. I
try to explain.
First of all, if i set limits more than swap space, one user can hung
system. But, if i set limit equal half swap space, two different users can
hung system.
Than, i don't set limits for root process. And combinantion "squid +
Netscape with java applet" from root may hung system.
While 3.2-system can't simply kill this process like 2.2.8-system? I think,
killing this process -- best solution.
Good luck,
Alec.
