I recently noticed my RAM problem. When I start any application it increases RAM usage but even after I close it RAM usage doesn't go down. Instead when I restart that application RAM usage goes up again. Using ubuntu 10.10

View 3 Replies View RelatedI've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
Code:
[root@server1 ~]# free -m
total used free shared buffers cached
Mem: 12011 7946 4065 0 4 23
-/+ buffers/cache: 7919 4092

I've made custom launchers for programs that can only run in terminal. They open fine within the Terminal window, but it closes right after the program is finished, before I can read the report.
Is there a way to keep the Terminal window open, using launchers? I don't want to manually type the commands after opening a Terminal.
I run the ping command using system() in C. It start pinging the desired destination but when I close my application it continues to ping. Is there any solution that as soon as I close my application it also stops pinging. Any change required in my C code?
View 2 Replies View RelatedI've wondered for years how it works and how I can change it. For example, opening a document with vim, or opening a man page, and then exiting out of it will sometimes (depending on the distro) clear the screen and leave your prompt at the very top. other times, it leaves the contents of whatever you had open on-screen and your prompt is at the bottom.

View 8 Replies View RelatedWe run Jboss app server that of course is all multithreaded under one JVM. I have couple of question regarding monitoring on per thread basis:
1. Is there a way to see which thread is bound to which CPU core?
2. Is there a way to see the CPU, Memory usage per thread? Something like prstat on Sun box which is real time and gives detailed information about threads per CPU
i have a c++ application that consumes a lot of run time memory. It is a very large project with a lot of sub-modules. My target is to reduce the runtime memory usage as much as possible. Therefore i would like to know if there is a tool that i can use to profile the code (note that i am not interested in checking for memory leaks / corruptions so Valgrind is not for my purpose) I need to know which module has the most static data like large arrays or a lot of variables to know where to start reducing.
View 3 Replies View RelatedI currently have two internet interfaces installed, one is ethernet (eth0) and the second is wireless (wlan0). Many command line applications allow you to specify which interface should be used, but many gui apps don't provide this option or at least I haven't found it. I have some questions:
1. How would I tell Firefox to use only my wlan0 interface? If it's possible in Firefox, is this also possible with Google Chrome?
2. If a program doesn't provide a command line argument to support this, is there a standalone application that could help manage preferences for multiple applications?
I was trying to have a go at installing MAC on my dell alongside Ub and W7. I copied the grub2 to the first part of my sda5 so as to put the mac loader in MBR.I have since repaired grub2 back to MBR.But now my beloved Ubuntu starts up then continuosly increases RAM usage till 90% then SWAP 90% even when no application is running!!
View 2 Replies View RelatedI just wanted to use a network bandwidth usage monitoring application. Scenario: I am using an EV-DO based USB broadband modem with a limited GB plan. For additional data usage they charge per MB. Currently I use either wvdial (mostly) or pon to start the connection. So if there is any network monitoring application which could log time used and data used for the session, it would be great. Actually debian has too many different network monitoring applications, But I am not sure which one suits well for this purpose.
View 5 Replies View RelatedI am facing an high CPU Usage 800% in a(Quad CPU, RHEL 64 bit kernel) with my C++ application .
The details are below:
1)The C++ Application has been compiled in RHEL (2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386 GNU/Linux)32 bit server(Quad CPU 8 cpu) in Dev lab. When this application has been tested for 12 hrs in the Dev lab, the CPU usage is varying between 20% to 50% .
However, when the above C++ application deployed in production which is RHEL (2.6.9-67.ELsmp #1 SMP Wed Nov 7 13:56:44 EST 2007 x86_64 x86_64 x86_64 GNU/Linux)64 bit server the CPU usage is found to be increasing constantly to 800%.
2)When the CPU reached to 800% in Production Server, we have taken the pstack of the C++ Application process by using the command pstack p [captured thread id ] and we found that the pstack is showing the high CPU
usage (800%) in below libraries:
If there is any GLIB /pthread library/any other differences between 32 bit and 64 bit kernel. Since the application has been compiled in a 32 bit kernel and deployed in 64 bit kernel. Please provide your support on the same.
I have a desktop PC that I built back when I was a teenager, running Ubuntu 10.04 LTS and nothing else. I love it, but for one thing: the dang CPU usage hits at least 99% whenever any application besides Xorg is open and running. This doesn't affect performance too much, but if Windows XP Home Edition never gets close to 100% usage, then I figure there's something going on.

I was trying to get the status of memory usage and disk usage using sigar in windows and ubuntu. done this in windows by just copying the sigar library into jdk library. But i was unable to do so in ubuntu. I've copied the library to java-6-sun library but still can't run the program.
View 14 Replies View RelatedI'm running into a problem where my system is running out of disk space on the root partition, but I can't figure out where the runaway usage is. I've had a stable system for a couple of years now, and it just ran out of space. I cleaned some files up to get the system workable again, but can't find the big usage area, and I'm getting conflicting results.For example, when I do a df it says I'm using 44GB out of 58 GB:
Code:
[root@Zion ~]# df -h
Filesystem Size Used Avail Use% Mounted on

Several times now my PC with Ubuntu 10.04 LTS installed wont close down. I click on all the appropriate buttons but the system doesn't shut down. I have to press the on / off button on the computer to end my session.
View 6 Replies View RelatedI have been using Ubuntu 10.04 LTS for several months and recently the system has stopped closing down cleanly. It starts okay and runs just fine, but when I come to closing down it doesn't do anything after I've clicked on the shut down button. The same happens with the restart button. I have been closing the system by pressing the power button on the front of my tower. I have no idea as to why it won't close ... I haven't installed any extra software, so I guess it's a system problem. Closing down by pressing the power button cannot be doing the OS any good, so I could do with a fix ASAP on this one.
