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?..
View 8 RepliesHow do you find the parent process of zombie processes?
When the child process is something where the parent is not entirely obvious...
Is there some way to list processes in tree format or something?
I have a zombie running on my computer(Ubuntu 10.10) and although I have tried killing it using the processes PID number it won't die.
Tasks: 137 total, 4 running, 132 sleeping, 0 stopped, 1 zombie

1733 stephani 20 0 0 0 0 Z 46.7 0.0 52:34.34 transmiss <defunct>
Transmission has being running for almost 60 minutes and is consuming a very large amount of the CPU.
I got indication of zombie process via top command
Code:
Tasks: 321 total, 1 running, 319 sleeping, 0 stopped, 1 zombie
I don't have 'Z' indication on 'Status' column
How could it possible to identify this process ?
i am bit confused about the two process that is zombie and orphan procees,both is different so what is the exact difference between the two process that makes it different and if there is no parent process then init adopts the children in both the case.

It is an openvpn process but I cannot retsrat the service as I alreday have another openvpn service running on the server so when I do openvpn service restart, it won;t know which service to restart.
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.

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
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

When this problems occurs the firefox processes are not terminated by the 'kill' command. Example

I am working on an issue in mishandling of mutex. A process was holding onto to a valid mutex for running, within this routine, it created a local mutex variable, copied the content of the valid mutex into this local mutex variable, freed the valid mutex, then used the address of the local mutex variable as the parameter to functions pthread_mutex_unlock() and pthread_mutex_destroy(). It was observed that CPU load 100% with scheduler staying in a loop. The program was halted. I try to seek an explanation to the relation between the CPU load and mutex mishandling in this scenario. I also hope some one will share the experience how this bug might manifest into problems on other platforms.

A while back, I put a site up under a LAMP setup, and followed a guide from ubuntuforums that I googled to set up SSL encryption for the site.
That site works great, but since then, I've added some other sites to the same LAMP server. They load fine as well, but if I type in https:// before going to the latter sites, the browser attempts to redirect to the first, and warns that it is a fraudulent certificate, and that I'm at risk by going to the site.
Obviously, it isn't an attack site, the certificate is just set up for only one domain. How do I prevent my non-SSL sites from redirecting to the SSL-encrypted site?

View 2 Replies View RelatedI made the terrible mistake of upgrading my live Debian Lenny web server with the the dist-upgrade option in apt-get. I didn't realize this was actually an unstable upgrade and now I have had to make all sorts of choices of what configuration files to keep or upgrade ect. The apache conf files were actually bad after the upgrade and I had to replace them with the backups (phew) and the system is currently still up and running. However my virtualmin installation is no longer working due to a issue with perl ( but thats another question I guess to ask somewhere else maybe ). Anyways... I'm very scared to restart because my server is co-located somewhere else and Im the only one who has ever worked on this server so I would need to go there and fix it myself if it doesn't restart. Basically I have two questions.. is there an easy way to move back to stable packages..If so is this recommended?
And also I'm currently trying to fix some broken dependencies in the package manager but when I run "sudo aptitude -f install" It keeps telling me it is going to remove all of these packages (listed below), some of which I know are very important to the system and I cannot figure out why it would keep trying to do this. I get an error on "phonon-backend-xine" whenever it tries to upgrade just saying this

I installed some desktop related packages a while back like gnome-desktop and I know the package is related to this, but all I really care about is making sure the server stays online and not about the desktop packages. I tried just removing kdebase-runtime and anything else that is dependent on it, but it wont let me do anything at all without fixing this broken package.
I really would just like to go back to lenny stable again but I know its probably too late since I already had it install a new kernel and grub 2 (auto configuring my new grub.list)..

I started the update process in my new Ubuntu Studio install.
My understanding of the update process is:
1) Downloads all of the update files (in my case 214)
2) It performs the necessary installation of these files.
My machine locked up at the 70% done part during step 2.
Now, when I try to boot/load the OS it stalls at the splash screen.
I am not even sure I can get to the recover part from Grub yet, but if I can...
Is there a command that can start the update process without having to download the data again?
For a diskfull node (the OS installed in a disk), I can use the 'insmod' command to insert a kernel module into the kernel. And after the reboot, the module is still in the kernel. I have a question here: how, when and which kernel module will be loaded in the boot up process for a diskfull node?And for the diskless node, can I use the chroot or some other ways to install the kernel modules into ramdisk, so that kernel module can work when the diskless node boot up? I think it needs certain mechanism to load the kernel like the boot up of diskfull node.

I'm new to the linux world and its been quit sometime since i've done any programming. However, I'm writing a program which simply calculates the load average of a process. In doing this I need to use the uptime command for linux in a java program. I've done a little bit of searching on the net and it mentions this is possiable by using java runtime command. Unfortunatly though I have yet to find a working example of this. I've tried just simply reading the /proc/uptime file but I have no clue how to format the 2 numbers in seconds to make it the same as if you just typed in uptime in the linux command prompt.

I have run Ubuntu on my laptop for several months. The last few weeks for an unknown reason when I click on something(nothing that seems related)I start getting many notification on the bottom panel and it just continues until I shutdown my computer but pushing down the off switch, the only way to stop it.
I have tried computer janitor and only get an error message that it can't run because it thinks synaptic or another item is running when it is not. I am TOTALLY lost when it comes to fixing issues in Linux but I like it and want to keep it on my hard drive. Where to start and remember I am an idiot when it comes to Linux.
Also some program's seem to crash for no apparent reason.
I just loaded one server, and want to load another server in the same exact way, just with a different name and IP. Can I somehow use the anacanda.ks from the old server if i change the IP and name in that file?

Or would I want to get Sid? How unstable is it?
This is for a desktop by the way.
one tell me the internal working of kill command. that is how it kills a process internally or from where it picks file to continue its process.
