Software :: How To Allocate More Than 2GB Memory For An Application On 32 Bit?
Oct 6, 2010
Can anyone tell me is there a way to add more than 2GB memory application in a 32 bit server? I found on many threads that it is not possible to set memory limit of a particular application to more than 2GB. I am using Fedora release 8 and trying to add more than 2GB memory to tomcat. If I modify the variable CATALINA_OPTS in /opt/bobcat/bin/catalina.sh (Startup script of tomcat) and add a value greater than 2GB for memory, tomcat wont start.Is there any work around / Kernel Patches available? Suggestions??
i just recently installed ubuntu 10.04 onto my laptop. its running as a dual boot. i only allocated about 10gb of memory and have already run out. is it possible to allocate more memory afterwards
and another bug that i am having is my shift key is not functioning properly. if anyone happens to know this issue too. so i can't do exclamations of periods, capitalizations, etc... how would you remap your keyboard
I have mounter ubuntu karmic 9.10 on a XP sp3 using vmware,i wanted to move some files through share.everything went well for 2 hours then i keep getting Cannot allocate memory.
I'm running a quite complex model, and it's taking me around a week to complete the run, and one of my colleagues says that he can run it in one-two days. After looking to several forums to know how does it work, I've seen how the memory is used (using the command ps -A --sort -rss -o comm,pme), and the model run just takes 0,3% of the memory. I bought a 4 cores and 8gb of RAM laptop to be able to run the model fast, but I don't know how to allocate the use of the memory to concentrate it in developing that task. Is that possible?
I am running BWA (burrow-wheeler alignment) and, keep getting an error that there isn't enough memory allocated. How do I change the memory allocation? I'm working on a good quality desktop only a little over a year old, so having the memory shouldn't be the problem.
This is a clean install of Debian Lenny, using KDE3.5.10 desktopHave followed these instructions:http://wiki.debian.org/ATIProprietary
Using kernel 2.6.26-2-686, I think the fglrx module has been built correctly. orac:~# modinfo fglrx filename: /lib/modules/2.6.26-2-686/nonfree/fglrx/fglrx.ko
I just switched over to openSUSE about a week ago from Ubuntu and I just purchased an Asus N13 PCI-E wireless network adapter which uses an RALink 2860 chipset. I plugged it in and openSUSE was able to detect it and everything but when I went to go configure it using YaST, it wouldn't be able to scan for networks.
So, I reinstalled my old adapter, downloaded the latest source from RALink and compiled the drivers. When I tried to use insmod on the new .ko that was compiled, I got the "Could not allocate memory" error.
If you need dmsg logs or anything else, I can reinstall the card and get those.
I went to an interview last week and there was this guy who asked a simple question that i have been trying to solve for a couple of days. I tried google but i just cant get the search keywords right. The result were just useless. Well, the question is : "How can we allocate a limited memory to a process before we start its execution" well, the question is related to an X11 system so may be some flags must be set to limit its memory.
I am developing a code where I need to store the planes of an object in a tree & also i need to store it in a list for further processing ... when I try to allocate using malloc the memory allocation when i checked this in internet , I came to know that it may because the memory that I am trying to allocate may be more than the size_t variable.
On my windows console, i have installed sun virtualbox. I only have 768MB ram and so i downloaded a trial version of eboostr. I thought it would work, but when i tried an install of 11.2, also, i tried a debian install, it did the same thing, it froze up in the middle of the install with the error Code: unable to allocate and lock memory. I guess that eboostr doesn't work, but is there a way to use a flash drive as ram in virtual box?
While Apache is off, then everything is OK, but if I start apache server after some time I get messages "Unable to fork: Cannot allocate memory" when trying to do some commands with ssh(dir,rm,top and so on).
After updating to openSUSE 11.3, and restarting my computer, I placed my computer in sleep(suspend to RAM) mode, and I lost my internet connectivity. I noticed that my computer was only connected through ethernet. After entering "dhclient eth0" in a terminal, I received the following output.
Code:
RTNETLINK answers: Cannot allocate memory
This is the first time that I have had issues with connecting to the Internet using Ethernet.
My mail server stopped working this weekend, when I got in today I restarted and all the emails came through. The panic_log shows: daemon: accept process fork failed: Cannot allocate memory several times over the course of a few minutes. Can anyone give me advice on troubleshooting this one?
I am writing a function(in C language in Linux) to initialize an array of a structure from a mysql table by calling a function by reference but I have a problem with call this function by reference . this is my program:PHP Code:
I am using malloc and frees a lot in my program. It shows its allocated but when i remove it doesnt show as the memory is removed(I am using the top command to view VIRT memory usage). If this continously grows what would happen to my program (Will it go out of memory?)
I get errors trying to virtual IPv6 Addresses i a lab environment. It works fine up to 2033 (?) adrressses, but when I try to add more i get "Cannot allocate memory" error:
I recently had to move to a new machine, everything went well except for one thing. I did fresh installation of LAMP server all with default configs. Every time I'm using PHP script to that invokes include, require or require_once I get the following error:
Code: Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 7680 bytes) in /var/www/index.php on line 2 index.php file: PHP Code: <?php include "index.php";?> icukapi.php file: PHP Code: <?php echo "test";?>
My memory_limit in php.ini is set to 20M. I tried to increase that however it didn't quite work. PHP seems to allocate all possible space and return that message every time i try. If somebody has an idea of how to fix it I would be more than grateful. I spend quite a long time searching for an answer however the all things i found suggested increating memory_limit which in this case doesn't work.
Do notice the line in the above quote ""sh": java.io.IOException: error=12, Cannot allocate memory."
The server will generate a world, but you can not connect to it using the MC client. Does anyone know what the problem is? I have googled for this problem for literally the past 4 hours and I am getting no where.
I'm searching a good suse monitoring application. I want to monitor performance(cpu,memory) also process,login to system, I want to run some automatically script when process down, send email.
I have a very weird memory issue (as you may have guessed from the title). There's a discrepency between the memory accumulated by the various applications (using "ps -eF" to collect that) and the memory reported by system monitor/"free" Basically, I have around 0.5GB of memory that is not occupied by any application, but is not free as well. (It is not used as cache as well)
We 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.
Whenever I'm running my application process, I've 1M physical memory usage is increasing for every 2 hours.This I observed using 'free -m' command.But 'top' command did not showing any increase 'RSS' size.It is same as it was started initially.Even though I stopped my process,the increased memory was not released back. If I start my application process then again memory usage start increasing by 1M for every 2 hours. increase of memory usage observer with 'free' and that too when my application is running, but top command is not showing any change in the RSS sizeIf my application is leaking any memory which is allocated by new/malloc, that should be released back whenever my application exit and the size increase will be show through top command for that process, right? This is not happeningThis proves that there is no potential leaks in my process.But why physical memory is increasing when only my process is running?
