View 2 Replies View RelatedProgramming :: Why The Stack Size Limit
May 1, 2011Why is it in Linux that there is a stack size set by default? And why is it so small? (My system is set to 8192 kbytes.) And why is there a default limit on the stack size when the max memory and virtual memory size are, by default, unlimited? (Aren't they both fed from the same place ultimately?)
Reason I ask: I want to use recursive functions in my programming a lot more. Problem is, if the language (or implementation) doesn't happen to support tail-call recursion, then I can be pretty well certain that the first huge problem that gets thrown at my function is going to kill my program because the stack size limit is going to be quickly reached. Obviously, I can change the stack size limit for my own computers, but it doesn't feel so great knowing that most of the people who copy and execute my code will have probably have overlooked this. Anyway, does anyone know: is this small default stack size limit just one of those historical artifacts, or is there some technical reason for it?

View 4 Replies View RelatedUbuntu Servers :: How To Decrease Thread Stack Size
Feb 5, 2010Desperate to reduce RAM usage of my tiny VPS running Ubuntu 9.04 and Apache2.2.11, here I saw that:
On Linux, each child process will use 8MB of memory by default. This is probably unnecessary. You can decrease the overall memory used by Apache by setting ThreadStackSize used by Apache by setting ThreadStackSize to 1MB in.
So I tried to give the suggestion a try. But when I append:
ThreadStackSize 1000000
in my /etc/apache2/httpd.conf <IfModule mpm_prefork_module> directive, and restarted apache, it failed with this message:
Invalid command 'ThreadStackSize', perhaps misspelled or defined by a module not included in the server configuration
So I figured out that the relevant modules are neither enabled nor available on apache2. Now I am wondering whether there is a way to decrease the ThreadStackSize without the need to compile apache from source? If not, what should I do?

Jan 5, 2011Why the thread stack size can not be changed after calling pthread_attr_setstacksize & pthread_create in a dynamic library? Detail: I write a file thread_factory.c and plan to build it and produce a dynamic library (libthread_factory.so) In the thread_factory.c , there is a routine
[Code]....
And after this, there is application, it will call fct_thread_create(STACK_SIZE_256KB), and then call pthread_attr_getstacksize(), but the stack size return always be a fixed value 0xa01000. (I tried this on Fedora12) But if I build the application source code with the file thread_factory.c directly, the stack size return is right as my expect. I checked the source code of glibc about the routine pthread_create() as below:

General :: Find Out How Much Time An Already Running Process Is Spending In User And Kernel Spac?
Jun 8, 2011I am currently struggling with one of my tasks.I was asked to find a way how to determine how much time an _already running_ process is spending in user and kernel space.E.G. <some tool> <pid>[Control] + [c]<pid> spent 12.1 seconds in user and 1.52 seconds in kernel space.Does something like this exist? Basically I guess I am looking for something similar to time, except that the process is already running.So..a) Is there a tool which fulfills this task?b) Is there a way to write your own software which does the job? Is it even possible to code something I am looking for?I recently found strace -c -p <pid>, but well, this is not exactly what I was looking for.

Programming :: Rules To Set The Pthread Stack Size - Compute The Memory Needed By Each Thread?
Jul 26, 2010i have an application that launches several pthreads, i know that the default size used by Linux is 8Mb for each pthread. However i would like to optimize the total memory usage by my application by decreasing the default stack size of each pthread to the needed resources. My questions:
- Are there any rules to set the pthread stack size.
- How to compute the memory needed by each thread.
- Is the malloc call inside a thread counted from the stack size of the same pthread?
Networking :: Running Iptables Break The TCP/IP Stack?
Feb 14, 2011I mistakenly ran 'iptables restart' on a server that was not set to run iptables. Immediately, the server quit making outgoing connections on port 80. It has problems completing a traceroute when another machine on the same VM Host can do everything just fine. One of our best networking technicians diagnosed it as issues with the TCP/IP stack on the OS.
I know that iptables is off, allowing all trafffic incoming/outgoing.

Debian :: Running Same Process Multiple Times(from Another Account) / An Instance Of Newsbeuter Is Already Running Error?
Aug 6, 2010Sometimes 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.
View 1 Replies View RelatedFedora :: Xsane Page Size Setting - Cannot Find A Page Size Anywhere In Any Of The Buttons
Jun 5, 2010I have a Canoscan LiDE 30 scanner which works fine in Linux. I haven't used it in months, and never since moving from Jaunty x86_64 to Fedora 11 x86_64. This evening I suddenly need to scan two pages to send to someone via e-mail, and the recipient is desperate to receive them. Naturally, Xsane has decided this is the moment to screw me.
The problem: I cannot figure out how to tell Xsane that the page size is 8.5 11. It insists on scanning only the left side, 3.99 x 11. I cannot find a page size anywhere in any of the buttons.
In Preview I once got it to scan the entire page, but could not figure out how to save the image to file. Subsequently I have not been able to figure out how I did it. In any event, scanning from the small main window always scans 3.99 x 11. Adjusting the scan area manually in the Preview window allows me to change the size area in the small main window to 8.5 x 11, but when I then scan from the small main window it reverts to 3.99 x 11.
I have scanned the document a hundred times at least, each time trying different buttons, but nothing has succeeded in getting the full page.
Software :: How To Get Size Of Memory Used By Each Process?
Jul 25, 2009I need to know, what process for what purpose is using memory in my machine. ps utility with various options seems to give not exactly what i want, i.e. if i sum all the values like RSS, VSZ or some other values related to memory usage, the sum is not equal (even approximately) to what i get using free|grep "buffers/cache".
How can i get this information? Even better, i would like to see contribution of every process, ramdisk, etc. to memory usage.

Mar 19, 2011I have written a script.
#/bin/bash
a=`du -sh /root/samplefolder | cut -f1`

[code]....
The aim of this script is, when the folder reaches 20M then attributes will be set to that particular folder so that no newfiles and folders cannot be created or copied to that samplefolder. whenever i copy a file morethan 20M to that folder its getting copied fully and then the attributes were applied. But i dont want this to happen, when the folder reaches its maximum current write operation to that folder should be stopped automatically with a error.
Ubuntu :: Keep A Process Running From Ssh
May 21, 2010I 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.
