Description Carmen Piper 2003-04-28 20:26:26 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020830

Description of problem:
When invoked using a process name, killall sometimes leaves a straggler process.
 A kill is never issued on behalf of this process and the process is inherited
by init.



Version-Release number of selected component (if applicable):


How reproducible:
Sometimes

Steps to Reproduce:
1. Large number of processes are created with the same name
2. A killall specifying the process name is issued
3. Since it is not reproduceable every time, I do this in a loop.  
A script is attached that reproduces this behavior

Actual Results:  
One of the processes is left unkilled.  From tracing I can see that a kill is
not issued on its behalf.  The process is inherited by init.



Expected Results:  All processes matching the specified name should be killed.

Can you reproduce it on new distribution?

I tried your test (18 loops) and I cannot confirm this bug. 
I have FC-3.
