[-- Attachment #1 --] Jordan, I've been running FreeBSD for about a year and a half now, and recently ran into some problems with ram... after realizing it was probably the ram causing these problems, I swapped it out and began the wait to see if the problems would persist... after a short wait decided I need to put the machine through its paces and see if I could bring the problem to the surface... Well, I couldn't get it to show itself, but.. I was astonished to see that the box lived through it. So... thanks to you and the rest of the fbsd team for contributing to a great OS. Through all of the load I put on the machine, it would still switch consoles without hesitation, and a control-c killed the parent process immediatly, returning the bots to a normal usable state. Below is my load average done immediatly following my massive forking... bits@chaos:~>uptime 6:51PM up 1:12, 5 users, load averages: 917.77, 875.69, 572.58 bits@chaos:~> That was after about 10 mins of running the program, the source of which is attached. For some extra info, heres my uname -a: bits@chaos:~>uname -a FreeBSD chaos.schizo.com 3.0-BETA FreeBSD 3.0-BETA #0: Mon Oct 5 11:42:19 EDT 1998 bits@chaos.schizo.com:/usr/src/sys/compile/ChaosKern i386 Awesome work on the OS, keep up the good work...
