[Freebsd-hackers] What kind of a crash is this ? (kernel ? userland?)

[Remko Lodder]

i dont think it's a crash.

i think there processess sucking up your cpu / memory etc.
that is why your login prompt does not get any cpu cycli's
therefor never giving you a prompt...

I had it when i had a nice little .kshrc file which did a id,pwd,
and stuff like that to give me the nice little
remko:machine [path]$ banner,
but that took so many proces space etc, that the computer stopped
responding.


Hope thishelped you a little :)

userland?)


Hello,

I have become familiar with certain FreeBSD crashes - namely, I can tell the
difference between the kernel crashing, and the userland crashing.

If the machine is down, but I can still ping it, then the userland has
crashed - the kernel is still running, which is why it responds to pings.

But if it crashes and just reboots itself, then the kernel has crashed.
Oversimplified I know, but I am leading up to:

What kind of a crash is it if:

I can ssh to the system, it gives me the BSD copyright and the uname
message, but never ever gives me a prompt.  What is going on in this
scenario ?  What kind of things have you seen that cause a crash like this ?

thanks.
