I just had a look at how the sysctl variables are called and what the values are on my system: vfs.maxbufspace: 70942720 vfs.hibufspace: 70287360 vfs.lobufspace: 70221824 vfs.bufspace: 70221824 How can I increase this to more than 70 MB? Any help is appreciated! Greetings, Thomas. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
