Subject: Hidden PIDs in /proc

Message-ID: <200403231708.15812.AlberT@agilemovement.it> (raw)


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 .

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
