Programming :: Memory Corruption While Parsing In Multithread Program?
Aug 28, 2009language: C
OS: linux
I wrote a multithread program(approx 1000 thread have to run) and each thread has to parse a file(for each thread there is one file, ex:thread1 has to parse file1 and thread2 has to parse file2 like this....). I wrote "parse" program as follows. It is working well, if i create 50 threads. but if i run more than 200 thraeds Im getting doublefree corruption as follows:
Code:
*** glibc detected *** ./simulator: double free or corruption (fasttop): 0xb70007b0 ***
And some time I am getting parsing problem and error af follows:
Code:
powersetting.6607:1: parser error : Start tag expected, '<' not found (where powersetting.6607 is file name, when i check this file it is started with '<').
parse program as follows:
Code:
void parse_first(char* filename, int portnum, struct Poweroff *Powerptr1)
{
struct Poweroff *Powerptr;
Powerptr = Powerptr1;

General :: Memory Corruption Detected In Low Memory
Aug 22, 2010This is my first post in these forums. I'm still quite new to Linux (using Mint 9) so please bear with my not-very-articulate question(s)When I boot up and open up a tty terminal I get a message saying "Memory corruption detected in low memory." I've done an extensive google search about the issue and it seems not uncommon. I ran a memtest with no errors returned, so I'm sure that there's nothing really wrong with the memory; apparently it's a bug in the kernel that's causing this.

Weird behaviour I should mention is that when I check for NULL pointer in node->child[index], the unassigned values are not null anymore, they point to arbitary memory.
General :: Installed ASUS HD4670, Now Unable To Install ANY Debian Due To Low Memory Corruption?
Feb 1, 2010I have a desktop PC which initially had the Intel D946gzis mobo, its chipset as video controller, some RAM and so. There I installed Debian without a problem alongside WindowsXP.
I've bought an ASUS HD 4670 video card, installed it on the PC and now the installed Debian does not work, while the Ubuntu live CD refuses to run no matter if I set acpi, apic on or off... it throws me some low memory corruption at position just like shown here. With normal configuration, Debian throws kernel panic (keyboard lights blinking). Anyone have faced this before? Ideas? Thanks!! (meanwhile, debian hides in a virtualbox :'( )
Edited: Tried Ubuntu 9.10 x64 (due to the fact i've a core2duo at 2GHz) and it throws a kernel-panic to me (flashing caps and num LEDs). On screen, can be read different lines with things like:
[ 1.957161] [] rb_erase+0xd6/0x160
[ 1.957266] [] page_fault+0x25/0x30
Could it be something about this new video card having ddr3?

Programming :: Allocate Memory To A Program Before Execution?
Jan 3, 2011I 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.

View 3 Replies View RelatedSoftware :: Program - Information On Drives Space Memory
Mar 5, 2010A few years back when I was running Linux most of the time I used a program that gave me information on my machine.
It had different themes and such, and it would usually rest vertically along the side of the desktop. It would tell one information on drives, space, memory, I think you could even have it tell you the weather if you entered geographical information.
I know I'm being a bit vague but that's all I can remember, does anyone recall this program? It was pretty popular back then...so I wonder if it's still under development.

The display freezes/hangs, but the kernel is still kind of responsive because I can hit Ctrl-Alt-Del and after many seconds it reboots.
I can get it (Slackware 13.0) to boot this same kernel just fine from CD; it's only the normal bootup, after the install finishes, that this happens.
I enabled netconsole so I could see the messages, shown below, but there are no errors reported. The display corrupts and hangs at the "TCP cubic registered" message which appears to be unrelated to anything video-wise.

I can get someone to start it up, and get as much as I can before it crashes.From looking at the messages, it seems like it could be something going on with the swap, but I'm not sure.The messages are below.(The box is on the other side of the country from me, so I don't have a ton of info, and it's hard for me to get someone to physically restart it for me...so it's kind of a pain.)(You'll see a lot of errors related to SSHD. I don't know if that's because SSHD is the culprit, or if it's because I was connected using SSH. For some reason I'm leaning towards it being something other than SSHD.)

Debian Programming :: Memory Usage When Running Java Program
Jun 28, 2013I have a java program that runs on Debian as a background processor. Yesterday the Java program stopped running. I looked at the memory usage, the system only had 5MB memory left, so my guess is that the java program ran out of memory to use.
However, after we restarted the java program, we could see that the free memory count started to go up. It kept going up from 5MB to over 400MB. The increase of memory happened slowly, when I measured it, I could see that with each minute passing by, there were a bit more memory added into the free memory pool, and meanwhile, the java background process was running.
I wonder why this would ever happen. It's as if our java program first brought the machine done because it consumed all the memories, then after restart, it starts to give back memories.
OpenSUSE :: Created A Tab To Look That The Physical Memory In The System? Monitor Program?
May 11, 2010I have a system with 1 GB RAM. I'm running KDE 4. I created a tab to look that the Physical Memory in the System Monitor program, which I assume appears to look at the same stats that "top" looks at. In that Physical Memory tab I have 3 tables: Used Memory, Free Memory, and Application Memory.The Used Memory table shows that the system is using .94 of .98 GiBytes. The Free Memory table shows that the system has .5 GiBytes of RAM free.
However the Application Memory shows that only 339 M-Bytes of RAM is being used.Note that "top" shows the same info.So where is the other .6 GiBytes of RAM that the Used Memory table shows as being used?If I look at the process table which is supposed to encompass all of the processes running, including the ones for the OS, then it appears to add up to the 339 M-Bytes being used in the Application Memory table. Is the rest of the memory being held in reserve by the OS to be used as needed? If so, then why when another application is opened the Free Memory goes down instead of staying constant?I also noticed this memory "black hole" when I was running 11.0 on a system with 4 GB of RAM. The OS appeared to "take up" a large chunk of memory that was NOT being used by any applications and making it "disappear" - meaning that the applications were using about 1.3 GiBytes of RAM and Free Memory was showing only .7 GiBytes instead of the over 2 GB of RAM that should be free.
Ubuntu :: System Freezes On Running Pearl Program - Out Of Memory

I cleared my cache by running the following:

$sync
$sudo echo 1 |sudo tee /proc/sys/vm/drop_caches
$sudo echo 2 |sudo tee /proc/sys/vm/drop_caches
$sudo echo 3 |sudo tee /proc/sys/vm/drop_caches
but it hasn't helped.
Even Firefox has been freezing, so I basically cannot do anything on my computer.
