Hi all,

I discovered some "hidden" pid dirs in /proc :

root@emc2:# ls -lha /proc/ | grep 4673
root@emc2:# ls -lha /proc/4673/
totale 0
dr-xr-xr-x 3 albert albert 0 2004-03-23 17:02 .
dr-xr-xr-x 108 root root 0 2004-03-23 16:10 ..
dr-xr-xr-x 2 albert albert 0 2004-03-23 17:03 attr
-r-------- 1 albert albert 0 2004-03-23 17:03 auxv
-r--r--r-- 1 albert albert 0 2004-03-23 17:03 cmdline
lrwxrwxrwx 1 albert albert 0 2004-03-23 17:02 cwd
-> /home/albert
-r-------- 1 albert albert 0 2004-03-23 17:03 environ
lrwxrwxrwx 1 albert albert 0 2004-03-23 17:02 exe
-> /usr/lib/mozilla-firefox/firefox-bin
dr-x------ 2 albert albert 0 2004-03-23 17:03 fd
-r--r--r-- 1 albert albert 0 2004-03-23 17:03 maps
-rw------- 1 albert albert 0 2004-03-23 17:03 mem
-r--r--r-- 1 albert albert 0 2004-03-23 17:03 mounts
lrwxrwxrwx 1 albert albert 0 2004-03-23 17:03 root -> /
-r--r--r-- 1 albert albert 0 2004-03-23 17:03 stat
-r--r--r-- 1 albert albert 0 2004-03-23 17:03 statm
-r--r--r-- 1 albert albert 0 2004-03-23 17:03 status
dr-xr-xr-x 3 albert albert 0 2004-03-23 17:03 task
-r--r--r-- 1 albert albert 0 2004-03-23 17:03 wchan


Obviously this is a persistent process, not a process living only for the
second test lifetime.

After 2 days of headhake searching for possible rootkits, reinstalling all the
basic system, libs and so on (from a clean live-CD boot) ...
I noticed that these process seem all to use pthreads ... so, the question is:

is my problem related/solved by the initramfs-search-for-init-zombie-fix.patch
in the -mm1 tree ??

thank you in advance
