Your system has been up for 4 days, so that's not unreasonable. Keep in mind that swap usage is not a bad thing! It's simply moving unused blocks of memory to disk. What IS bad is constant swap usage (thrashing). Run 'vmstat 1' and watch the 'pi' and 'po' columns. If they are below 10, you're okay. -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
