Re: FreeBSD hang without panic
On the machine itself no messages are shown and the machine responds to repeated ENTER key presses with the login prompt. Once you enter root [ENTER] then no further responses (except line feeds as you press ENTER). What kind of hang is this? Could it be a DoS attack? Or is it some internal process hanging? I have a debug kernel but as the only solution is a power-off reset, I never get any dump. Any suggestions please where I might start to look, or services to experiment disabling? My very first instinct was hardware failure. It has all the right pieces: intermittent, came out of nowhere, weird problems as a result. But. In the interests of science: I know you said existing shells stop working, but does that include the secure shell? ssh into the box when it's frying itself and see what happens. Presumably you've checked the /var/log stuff already?

FreeBSD hang without panic
On a FreeBSD 5.2.1 box that has been in production a long time, I have had a new type of hang on two days this week, the type of which I have not seen before. (No recent software/hardware changes). Symptom: The machine is a web/email server only. It stops receiving new SSH/HTTP/IMAP/POP connections, existing shells cease working. On the machine itself no messages are shown and the machine responds to repeated ENTER key presses with the login prompt. Once you enter root [ENTER] then no further responses (except line feeds as you press ENTER). What kind of hang is this? Could it be a DoS attack? Or is it some internal process hanging?
