Process whithout a name

Eli_pok — Wed, 28 Apr 2010 05:03:47 GMT

Hi,

I have a process in RHEL 5.3 that has no name?!?
I saw it in glance as , and then checked the it with ps -ef.
It seems like there is no command behind the pid.
In ps -ef the CMD column is empty....
The process is the child of init (1), and is run under one of the users in the server (not root).

Any idea how it can happen ?

Unfortunatly not.
I use a stand alone lan so posting outputs is a bit problematic.

the ps -ef | grep PID looks like :
user 28197 1 1 Apr27 ? 00:07:47

and thats it.

I checked the top commnad and it does sees the command name.
How can it be that glance and ps -ef dowsnt see any thing but top does ?

hello,

you can use
ps -p 1234 -o args,comm
(with 1234 as your pid) to see more of the process.

Hi,

Do a "ps -ef > ps_out", and analyze the output with "cat -tv ps_out". Maybe the program runs with a name of a nonprinting character.
