I never found the problem. It went away when I re-compiled
emacs. Below is my question.

Hi.

Have a 'small' problem here. Emacs manages to crash an SS2. Completely.
This person is not doing anything special. Can anyone shed some light
on this?

There. That is about all the info I can find. (Can someone tell me
how to find more info, on what exactly happened?) Anyone have some
insight into this?

Thanks much in advance.

System: SS2 running 4.1.3, local swap, NFS the rest.
