Remove /proc/kcore

[Alexis Vasquez <lxvasquez usa net>]

Hi. everyone.

Suddenly I found my root directory "/" full at 100% usage.
the only strange thing I found was the archive /proc/kcore with about 500MB
size, but I don't know if I must delete it. but I tried
with no success it has -r-------- root root . I logged as root
but don't let me rm kcore.  and cat /dev/null>kcore either works.

how can i detect another big trash file?
maybe you can show me a little script to find and remove every core.

2.another issue is I changed the file /etc/inittab the init level
and put 5 in the level but when it show the graphical login it is too
big I mean the fonts.  

How can i put lets say 800x600 resolution?.

pd I tried xconfigurator and it didn't work.

thank in advance.
