How to do this depends on exactly what version of FreeBSD you are running. The best advice is to update to 4.5 or better, and set KVASPACE in your kernel config, and just build a kernel. Generally, you should know exactly what you are doing before you try this, since there is usually a lot of collateral tuning you should do for your application, if you really need to do this. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
