On kernels from 2.6.27 and further
To speedup the working of all processes as follows:
add to the boot line as grub starts: noirqbalance elevator=cfg
yast2 is more responsif and the processes run on all the cpu's not 3 and 1 as with irqbalance
speedup yast2: export aria2c
result: Gkrellm with a load as little as 5% overall i see all the cpu's working
OpenSuse shows me this on boot:
Skipped Processes on run level 5 early xdm cifs nfs xdm
On my fresh installed 11.4: I boot the desktop entry in GRUB, and it's doing a fast boot. It loads INIT and switchs to runlevel 7. Then the comment:
Code: init: No more processes left
Or something like that. after a CTRL+ALT+DEL and a press on enter during the driver load, it all works fine. Is that just a standard fault, or should I do something? If so, what?
Many processes enter in disk sleep mode and stops (Hang) and return to work after 10 to 20 seconds.
In System Monitor i get "Disk Sleep" like this:
My PC specifications:
Ram: 4GB
Hard Disk: 1024GB
Processor: AMD Athlon II X2
Display: ATI HD 4670
Motherbord: Gigabyte
System: openSUSE 11.2 x86_64
The problem still exists after system update and i try run other distributions like kubuntu and i don't get this error. I also change Hard Disk but the problem is still ongoing.
I dont want to use player like vlc to speedup the playback. I want to actually speedup playback in the original file. Its like I want video to be played 2 times faster.

I am using 11.04 64 with the Classic desktop. I found that dragging windows was terrible rough. Consumed CPU when dragged.
I loaded CompizConfig Settings Manager. Go to the bottom where the 'Work Arounds' are. Enable 'Don't wait for video sync'.
Made a huge difference for me. Able to make it look and work like 10.10 for the most part. But I like a clean old Gnome look and feel.

My system, setup as a server, has 9 kjournald processes and each one has many worker threads. FOr the most part they just sit idle but I do see one or two occasionally activate with disk activity (which you would expect).
However is 9 processes normal or am I getting stale processes that need to be looked into?
Just now Rhythmbox has stopped working. I can't restart it, so I thought I could kill the process to start it again. Is there something like the windows task manager in openSUSE or another way to list all processes and to kill one? I googled an found a few old threads saying that there is a performance monitor which is able to to that, but I can't find that either.

How can this be avoided or better dealt with than an occasionala reboot of the server, clearly not an optimal solution.
View 1 Replies View RelatedI keep the network window of System Monitor active on my panel to see if anything is going on with the network.
After the last upgrade, lucid has been having nonstop short, small bursts of network activity, showing in system monitor as received data of approx 60 kb, then 0, then ~60, then 0, continuously. This is occurring before any applications are opened.
Whatever it is, it starts to tie up the processor until performance is unusable.
The processes screen does not offer any clues, perhaps because the data transfers are so small and spaced out. It still should indicate what is tying up the CPU, though. In the attached screencap, you can see the network activity pattern in the system monitor window in the panel.
Is there any way to monitor what processes are accessing the network in order to see what is going on?
Actually there are three c programs double,half and square which respectively double halfs and square an integer , i have place .out file in sbin folder ,now they are processes now i have to concatenate these three processes like double half it return 8 how i will write the codes for it.

I had this error when installing and running a vncserver before, which I have now removed. However, the xterm's seem to remain in the system and are regenerating themselves. Should the pid IDs stay the same each time I run this?

GNU/linux kernel 2.6, Slackware 12.0.Hi:How do I know what processes are running?
View 6 Replies View RelatedI need to create a small list of processes in a monitor.conf file. A shell script needs to check the status of these processes and restart if they are down. This shell script needs to be run every couple of minutes.
The output of the shell script needs to be recorded in a log file.
So far I have created a blank monitor.conf file. I have gotten the shell script to automatically updated every couple of minutes The Shell script also sends some default test information to the log file.
how I go about doing this part ? A shell script needs to check the status of these processes and restart if they are down.
I have put in the conf file the below commands but I am not sure if this is right.
ps ax | grep httpd
ps ax | grep apache
I also dont know if the shell script should read from the conf file or if the conf file should send information to the shell script file.
I am trying to show only the processes that use more than 10% of the cpu. I have managed to get it to show the processes in use using:
ps -eo pcpu,cpu,nice,state,cputime,args.
Then I am unsure how to sort this information so it only shows over 10%?
I will be switching to Debian soon and have been forming a large script with a vbox test system to automate my system configuration when I switch.
When I install lamp (Or basically it's equivalent packages) apache and mysql start up automatically.
I could just use update-rc.d to remove the autostart but whenever there's a security or feature update for the package the files get replaced.
In addition, for some reason the system thinks it's a good idea to autostart half a dozen apache2 processes at the same time, sucking up a good 150Mb ram when not doing anything. (Anyone know why?)
How would I stop my system from doing this? Could I "chmod 000" the /etc/init.d files?
This morning I ran unhide on my Squeeze x86 netbook. The brute force process detection came up with ahidden process. Repeated runs of unhide with the system in various states continued to show the process,but with a different PID each time.(Or maybe it was spawning new processes and killing itself every second or so. A newer version of unhide,which I compile from source, did describe the process as "maybe transient" or omesuch. Anyway, I've unhide on Squeeze before, and I know that detection of any hidden process is absolutely not normal.)Also, rkhunter found some hidden directories. Of particular note, I think, is /etc/.java, which contains evenmore hidden stuff. It *might* be system-wide preferences for the JVM, but somehow I doubt it.
So, I have two questions...1. Do I really have a rootkit or trojan infection? It looks like it, but I want confirmation that I'm not chasingphantoms. (Or that I am, whichever.)2. If so, how can I prevent a recurrence? FWIW I was running without iptables or any other firewall, but I madesure all my ports were closed; and I did most of my browsing through Chromium, which should have pretty
I replaced my gnome with openbox some time ago, some of the gnome utilities still boots at at the start and I love and use most of them.

Why does the system while booting not just simply add the necessary programs for the next level by starting them, thus making the stopping of specific tasks not necessary and certainly speeding up the boot process?

And it comes and goes with the cpu usage. cpu1 will run at like 9 or 10 percent idle while cpu2 will run at 100 percent all the time. I am not sure whats going on. But id hate to have to start from scratch again begins I just got it set up the way i want it. And the network activity keeps having spikes when I am not online. I've scanned with multiple port scanners and nothing seems out of the norm.
Is this normal? using Lucid Lynx. Also happened to me on Karmic.
View 4 Replies View RelatedI installed the compiz config. app, then changed some values. and after that I uninstalled it..
Now I see two or three processes running in System Monitor
I want to get rid of all that. how can I do that?
I've just installed the Netbook Edition of Lucid on my MacBook, and it works great, with two issues:
First, each time I start, the computer is extraordinarily laggy (pretty much unusable), until I run System Testing for video, and go through the whole process. Then it seems to work great. Also, I'm having a 100% CPU issue, which switches between my two CPUs. There was nothing under "my processes" that showed any kind of heavy use. But, under "all processes" was something called Backend. I killed the process and now everything seems to be working just fine.
I did some unfortunate dragging I think and now most of my windows which were open before are not there anymore. When I go to processes, I can see that they are still there. E.g. I had a terminal window open and now the window is gone but I can still see a bash process in the list
