A "make it do something" test he runs on Linux, and on the SCO Openserver boxes on the production floor, killed FreeBSD very quickly. It was quite embarrasing, being so simple. It's just a looping batch file which appears to rapidly eat all of swap, while he insists the other boxes handle it fine. >How-To-Repeat: Create a file called "looptest", which contains: ls -l ./looptest Make it executable and run it. System performance drops and before long it's griping about lack of swap and attempts to log into the other virtual consoles fail. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
