Software :: Sending Thread To Zombie List?
Feb 1, 2010
these are the functions I am using for creating threads..
#include "mythread.h"
/** Global Data **/
tcbList_t *readyList = NULL; /* Ready list */
tcb_t *runningTCB; /* Currently running thread */
tcb_t mainTCB; /* Starting threads's TCB */
[code]....
The function endThread() currently simply ends the entire program, not just the terminating thread. I need to modify the function endThread() so that it will place the terminating thread on the zombie list and switch to the next ready thread if the ready list is not empty. If the ready list is empty then endThread() should switch back to the main thread (the state of the main thread was saved in "mainTCB" by initiate())... and, in createThread() space is malloc'd for the thread's TCB and stack. This space should be freed...

In short our required is that we are creating a share library which can be loaded by a process and that share library analysis the process which load it. Since share library is in address space of the process so I need to find out how many threads created by the process and what is status of their stack trace etc.
So I am looking for a way to get list of threads in running process.

I am going to use "pthread_setaffinity_np" to bind a thread to a specific core. My application has two threads. I have used mutex to assign a specific id to each thread and then bind that thread to a core different from another core. but it seems that the os assigns both thread to one core.What should I do to bind each thread to a specific core?

I received the following output from an rsync (3.0.0) command that was executed:
sending incremental file list
sent 77214 bytes received 484 bytes 155396.00 bytes/sec
total size is 254531170 speedup is 3275.90
What does "sending incremental file list" mean?

I'm trying to do a
find /photos/* -type f -mtime +365
to find all my pictures that are over a year old, but I keep getting argument list too long. How can I view what all the results are, even if it just dumps it to a file that I have to open?

Sometimes I find a process named 'sh' running under my username with the status 'zombie' waiting channel 'do_exit' on my system. Its ID increments by 4 every time System Monitor updates its display.
Today, it was there immediately after booting The only thing I did after logging in is start the System Monitor
I can't kill it since its ID changes too fast.
I don't know how it gets started, but it bothers me since it is behavior I would expect from something that is trying to hide.
If I hover over its name, the tool tip contains 'sh'

Sometimes (rarely) when I try to open VLC it wont open, but it stays in the background and takes 98-100% of one core.
The problem is that I can't kill that vlc-process.
Code: Select allkillall vlc
will NOT kill it
and
Code: Select allkill 31641
won't work either
top shows
Code: Select allPID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
31641 xxxxxxxx 20 0 1320248 64384 39120 S 100.0 1.6 44:51.94 vlc
Is there any way to kill the vlc-process (without booting the machine)? I also tried the "killall vlc" and "kill 31641" as root with the same results.
I have Debian jessie and the only "nonofficial" repositories I have enabled are
#google chrome
http://dl.google.com/linux/chrome/deb stable main
#Backports
deb http://httpredir.debian.org/debian jessie-backports main
And from those I have installed only chrome, and wine-development, and I dont think those could have anything to do with this problem.
Booting the machine does work, but I don't want to boot my machine just now. This happens about once per week

For the past week or so every time I've tried to launch Firefox it would freeze within a few seconds and the process 'firefox-bin' would go Zombie. I would force quit FF and then try and reboot the machine. Then I would get an error before restarting informing me that 'firefox-bin' is nonresponsive and it gives me the options to cancel or reboot anyway.
I'm not entirely sure what's causing this, however I have an inkling suspicion that it's being caused by Netvibes and/or Google Voice, which doesn't make sense because I've been using both services for quite some time now and this is the first time I've encountered any problems.
Has anyone out there encountered somethingt similar? Update: I've been browsing for about ten minutes now without launching google voice or netvibes and I haven't had any issue yet, so I'm pretty sure those two are causing the problems. But why?
Update2: There's a chance that I could be wrong, but I do know that GV and Netvibes are causing the crash as well as a whole slew of other random websites. I was browsing a website earlier (can't remember the name of it anymore) That also caused my browser to freeze.
To the best of my knowledge I haven't done anything different since this issue started, all I know is that I can no longer safely and conveniently brows the web on this laptop anymore.

I'm writting a program that uses a USB webcam. Sometimes the program crashes and exits, but sometimes it crashes and becomes a zombie process, which I can't kill even with -9/-KILL signal. When that happens, all access to th USB webcam is totally interrupted and all attempts to communicate with it fail.I'm looking for a way to either force this process to terminate or to at least make it release the webcam so I can use it again. So far, the only way I've found to regain control of the camera is to reboot

Slack is 32bit. Frequently, firefox becomes unresponsive. I can close the window, but the process is not terminated. I am not able to restart firefox without rebooting.
When this problems occurs the firefox processes are not terminated by the 'kill' command. Example
Code:
tim@bart:/home/http/run/baker/cron$ ps aux | grep firefox
tim 3780 0.0 0.0 3356 1640 ? S 15:59 0:00 /bin/sh /usr/bin/firefox
tim 3792 0.0 0.0 3404 1696 ? S 15:59 0:00 /bin/sh /usr/lib/firefox-3.5.2/run-mozilla.sh /usr/lib/firefox-3.5.2/firefox-bin
tim 3796 0.3 3.2 316560 95712 ? Sl 15:59 0:21 /usr/lib/firefox-3.5.2/firefox-bin

I'm running 9.10 on an HP d530 SFF, Pentium 4 2.8GHz HT w/800MHz FSB and 512KB L2, 1.25GB DDR333 RAM, GeForce 440MX. In the BIOS I have ACPI S3 Video REPOST enabled, as well as ACPI S3 Hard Disk Reset enabled. Resuming had the same problem with either of these settings disabled as well. Install graphics driver is nvidia-glx-96, version 96.43.13-0. To my knowledge, this is the newest driver that supports the GeForce 440MX -- I attempted to upgrade to newer drivers for XBMC before but they do not support the card.
uname -a output:
Linux fahrenheit 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:05:19 UTC 2010 i686 GNU/Linux
When I attempt to suspend this machine it suspends fine, and will come back to life when I press the power button. I then get a hardware (text mode) cursor for a few seconds, then the screen blanks and goes black. At this point I can ssh into the machine and it is responsive, mostly, but Xorg is taking up 100% CPU and the fan spools up to maximum. The Xorg process is unkillable -- kill -9 won't do it. Load avg on the machine is high and it gets freeze-y for a few seconds at a time. How to get either suspend or hibernate working. This is a media box and we'd like the convenience of a quick resume time, but the ability to save electricity when it is not in use.

There are around 173 zombie process on my client's server, my question is whether zombie process on the server will make server's load unstable like it goes to 20-26 suddenly and comes down and goes high suddenly,will zombie process consume system's resource?..

I have written a simple script which has to find required patterns from a bunch of files ( where each file is around 2 GB each,which contain the output of seq 1 10000000000000) on an 8 core machine.I am current forking 6 child processes which run simultaneously on 6 cores of the processor & have to search for the required pattern in 6 different files & inform the parent process when a pattern is found using a PIPE.
The problem is,when a child process is done reading a text file looking for a pattern,it is becoming a zombie process.It exits cleanly when i put a $SIG{CHLD} = "IGNORE"; in the script.Can any one tell me whats going on & how do i improve the communication between child and parent processes?
Code:
#!/bin/perl
use strict;

Is there a library/system call that will return to me what CPU core a thread of execution is running on? I've looked for a bit on the net already and also in /usr/include and couldn't find one.
getcpu() and sched_getcpu() are two that I found, but when I include the appropriate header files (linux/getcpu.h, and sys/sched.h respectively), gcc says getcpu.h doesn't exist and the linker complains it cannot find the implementation in sched.h.
I'm sure I'm doing something really stupid or overthinking...
What I am doing is running an OpenMP application and specifying a list of cpu cores to run on with GOMP_CPU_AFFINITY. I want to make sure that each core is getting the same number of threads.
**UPDATE**
It seems that this code works, but only with glibc >= 2.6, and my machine has 2.5:
Code:
#define _GNU_SOURCE
#include <stdio.h>
#include <utmpx.h>
int main( void )
