Red Hat AS 2.1 crash.

Red Hat AS 2.1 crash.

[Eduardo E. Silva]

Hello, while mousing around we ran a command

find / -type f -exec grep pass {} \;

on a Red Hat Advanced Server 2.1 using kernel  2.4.9-e.12smp based rpm from
Red Hat. Well the machine panic when grep hit /proc/kmsg.

I ran the same command on a machine with a later kernel  2.4.9-e.30smp
withour panicing the machine. Although it hung up in the /proc/kmsg.

Has this been a confirmed bug ?

That would be a bug. Although I suspect it's also a case of "don't do that
then" - you _really_ shouldn't indiscriminately touch files in /proc,
since they often have magical properties.

The latter is not a bug, it's just an example of the magical properties of
/proc. Some files may _look_ like regular files, but you shouldn't depend
on it.

sounds like you're better off filing a bug with us (Red Hat) than on
lkml ... see http://bugzilla.redhat.com
