I found a problem, nay a very serious bug in red hat 6.1(kernel 2.2.12).
I login as an ordinary user and did as follows( in fact I wrote a faulty =
shell program and put it in a directory in PATH):
$ mkdir bin
$ cat >bin/hello
hello
^D
$ chmod 0755 bin/hello
$ hello
This system crashed after giving messages like:
=20
syslog: Out of memory
....
......
.....
init: out of memory
First I suspected that the problem is in kernel2.2.12. But when I =
booted RED hat 6.2 with this kernel and run the same culprit shell =
prog, the process terminated with the messge:
bash: Out of memory!
which it should do.
