Software :: Jbd2 / Sda1-8 What Exactly Is This Process That Keeps Running Every Few Seconds
Feb 12, 2010
I'm trying to figure out what this process is that pops up when I run PHP Code:
top -i
every few seconds
PHP Code:
jbd2/sda1-8
The best info I've found so far says it might be something to do with ext4 journaling, but I've never seen this before. I'm running 2.6.33-rc5 if that might have something to do with it. Further the process hasn't been popping up for the last 10 minutes or so, but previously it was occuring every 2 or 3 seconds repeatedly for a minute or so.
Is there any command to find out for how many Milli seconds a process is been running?s -a -o pid,etime | grep "process pid" gives the time in min:seconds. I wanted in milliseconds .
Is there any program to terminate process automatically if using more than 90% or 100% CPU time for more than 5 seconds? I have a program that opens a web browser, do some stuff on it and close it. But problem is that sometimes that browser starts using 100% CPU
Sometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.
Simple question: what parameters can be used to shutdown a computer running Linux/OSX in 30 seconds? I've always run Windows, where I would go shutdown -s -t 30 but the parameters are different. I've looked it up here but it will only let you shut a computer down at a specific time (like 8:00) rather than in a specific amount of seconds.
So i just finally installed Debian Jessie OS, replacing Ubuntu. But now it is running extremely slow. It's not internet connection. The internet speed is running fine (Videos load quickly), but it's like the system freezes every 30 seconds or so. A video can be fully loaded but still stops and starts constantly. Just browsing the internet, or non-internet things do the same also. I switched back to Ubuntu to see if it was different on there, but Ubuntu is running fine.
Linux bash inline command to execute a program and limit the resource.As I know, to limit the resource I can use ulimit command.But, the problem is when I set the CPU time limit 1 second, and then I want to execute another program with CPU limit 2s, the ulimit command return an error like this: bash: ulimit: CPU time: cannot modify limit: Operation not permitted and absolutely my program killed in 1 second.So, How can I make the second program running with the CPU time limit 2 seconds?
I am having a problem with my Fedora11, I am not sure wether it is software or hardware but this looks serious. My computer is running very slow and freezes up every few seconds. Every time I reboot I would get a kernel failure pop-up.
I am trying to install 11.2 but it keeps freezing. I press install and the Linux kernal loads and afterwards I get a black screen and after 30 seconds the DVD player stops running. I have also tried to the online network install and the exact same thing happens. I also tried a DVD I have of 11.1 which I know is good since I have successfully installed it on other machines and the result is also the same. My computer currently has a dual boot of XP and Kubuntu 9.10.
I am returning to Suse after experimenting with Kubuntu but thought I would leave the Kubuntu on the machine (prefer Suse but Kubuntu installed very easily on my computer). Could the Kubuntu be causing this problem or is the difficulty something else? I have also tried the safe install and the other options to no success.
I recenlty set up a headless linux home server by my router will my spare computer parts. I have NFS and even a COD4 server running on it for my friends and me. Because the box is headless, I take controll over it with ssh and start the COD4 server from there, but the problem is, if I close the terminal I have the ssh running from, it closes my server, meaning my desktop needs to be up and running the entire time. That kinda ruins the point of my server
So my question is, is there a way for me to run the command so that it will not close with the terminal AND that I can still send commands to the server.
Is it possible, using ps, to determine where a process is running from? I have two applications, both are identical and running in parallel directories, such as /app1/start.sh and /app2/start.sh. If I run ps -ef then I'm unable to tell the difference between the two
Using ps (or alternative), how can I tell that PID 123 belongs to app1?
If I run top, there's a process plymouthd always running, often taking a few percents of CPU. I found that "plymouth" would be a splash screen. My PC is booted already though, I don't need a splashscreen once it has booted. Is this a bug? How can I get rid of this process that always uses %CPU?
Maybe someone can shed some light on this process that is running. It is using my CPU about 100% since there are 2 instances of it running with about 50% used by each.abc_sieve_2.10_i686-pc-linux-gnuI've never noticed it running before and don't think I've installed anything except updates.
I am writing network module (LKM). I got process information by current->pid and current->comm. But now i want current state of task. I want to know the state of running the process. I dont find any information in struct task_struct structure. how can i get the state of current running process.
How can i get the notification of process which are currently running?
We wrote one script which is being fired for every minute, instead of that is there any to trigger the event from linux core implicitly if there is any change in my process(pid)?
I have not been able to find any information on this, mostly because I am sure I am searching for the wrong terms. Let me explain what it is I need to do.I have a timeclock process that needs to be running all the time on my Red Hat server. Right now, I manually start the process from terminal:Code:# ./timeclockThis runs the process inside the terminal. The only problem is that if I close the terminal by accident, the timeclock stops working. This is all well and good for now, until I get more timeclocks.Then I will need to have one terminal open per. What I would like to do is to make this process run at start up, and run behind the scenes (no terminal). At the same time, I need to be able to re-run the process (again, hopefully behind the scenes) in case the timeclock goes offline or the process crashes.I know very basic things about Linux administration, and I know it is possible to do this (as there are processes now setup by someone else that do this), I just do not know how. EDIT: An idea I had would be to make the script run every minute, checking to see if the process is already running, and if it is not, then to start it. That way it would automatically correct itself if it went offline.
I have stellarium 0.10.2 but whenever I run it, it does not save my settings. A look at its output is:

The failure continues for as long as the app is running.
How do you move a running process to the background? For example, type the command sleep 60 on the command line and try moving that process to the background.
I just installed Wine (1.1.3* dev release) and installed Notepad++ (OSS) and Net Meter (Freeware, the latest beta is actually OSS too). I also intend to install a few other things later. The only failure so far is the latest WinSCP So it made me wonder about what running a process/software as "root" actually means. When I use U.S.C or 'apt-get install' to install software on my computer, and type my password, it displays that keyring icon on my systray.
Does this mean I am root at that moment? And how about running wine, the wine processes, and any windows *.exe I'm installing and running? I basically am afraid that I am running all the wine-related stuff as root, even though there is no indication that I at least have elevated privileges. What is/are the worst-case scenario(s) about wine?
Firefox keeps freezing.the process keeps running.I've uninstalled firefox, installed different versions, ie 3.6, 3.7 etc, I've removed my profile folder in my home directory.same results. I've ran firefox as a SU and I get this output from the terminal
(firefox-bin:28892): GLib-WARNING **: g_set_prgname() called multiple times /home/josh/.gtkrc-2.0:2: error: scanner: unterminated string constant - e.g. `style' (parent won, so we're not deferring)
I installed Gnunet (a secure P2P program) on Ubuntu 10.10 using Ubuntu software centre but had difficulties getting it to work so removed it. However, the gnunetd process loads at startup. It is only visible when typing 'top' in the console and not in the system monitor list of processes.gnunetd --version tells me that it is 0.8.1b sudo apt-get remove gnunetd tells me 'unable to locate package' why the process loads and how to remove it? I can kill it in the console but would like a way of getting rid of it permanently.
i am using Ubuntu 10.04.1 LTS. i only ever contact my ubuntu machine through SSH. everytime i login, i do:
~/downloads/.dropbox-dist/dropboxd &
this launches the dropbox process and all is great. except when i log back into the ubuntu machine via ssh after a few hours, the process no longer exists. how can i get the process to run indefinitely?
I am trying to write a script that will look for a plugin and check that its running and if not start it Code: ps ax | grep -v grep | grep aseco.php The above should list the process, if I put it into terminal this is incorrect?
