The machine is mildly loaded, running http, ftp, pop3, smtp, telnet... as well as a low volume NFS client and server. Any suggestions as to how to fix these panics would be greatly appreciated. If more info is needed I can probably find it. Thanks in advance, Anthony. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
