The system goes well. However, somtimes, after uptime larger than 7 days or so, the system went into "semi-stop" state. At the moment while i am compose this mail, bbs.ee.ntu.edu.tw is in "semi- stop" state, and it have went into the strage states several times. In "semi-stop" state, console login is unavailable. When pressing Enter on console, it didn't show login prompt again, just stop there. In the mean while, httpd/smtpd/ftpd/innd also failed responsing. However, bbs(telnetd)/ gopherd/pop3d/named are still in normal state, providing services well. bbs/gopherd/pop3d are chrooted-static-linked daemon, named is the standard /usr/sbin/named (4.9.7-T1B). After previous semi-stop state, i've modified the ftpd to static-linked bin, to test whether dynamic-static relate to the situation. And the answer is not sure according to the situation now -- ntubsd[woju]:~$ telnet bbs.ee.ntu.edu.tw smtp Trying 140.112.18.32... (stop here) ntubsd[woju]:~$ telnet bbs.ee.ntu.edu.tw ftp Trying 140.112.18.32... Connected to bbs.ee.ntu.edu.tw. Escape character is '^]'. (stop here) Seems somewhat "better" than the dynamic-linked daemons(smtpd). The problem is rather hard since console(& any other type, say, remote) login isn't available, and don't know what's going on "inside". Has anyone encountered similar situations? Any comment is welcome. Thanks. - woju To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
