Using getrlimit I am setting the core file size to be RLIM_INFINITY. But still the core file is not being generated,although in /var/log/messages it says a core is being generated
View 3 RepliesFedora 12 gcc 4.4.1 I am doing some programming, and my program gave me a stack dump. However, there is no core file for me to examine.
So I did:
Code:
ulimit -c unlimited
and got this error message:
Code:
bash: ulimit: core file size: cannot modify limit: Operation not permitted I also tried setting ulimit to 50000 and still got the same error. The results of ulimit -a:
Code:
$ ulimit -a

Why 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?
I was just testing specifying limit on file size to a user and have added the following to /etc/security/limits.conf bob soft fsize 100 This basically should have said not to allow bob to create anyfile greater than 100Kb in size.
But the interesting thing is, if bob already has any file which is greater than 100Kb in size, it even doesn't allow to log him into the system both from console and SSH. Also nothing is logged in logs.. How do I configure it so that, bob can login to the system even though he has any file greater than 100Kb (but doesn't allow him to create file which are greater than 100Kb) ??
I have 2 directories in my home folder that I would like to set a size limit on. The directories are ~/backup and ~/temp. Is there an easy way to limit the size of a directory without having to make partitions?
View 4 Replies View RelatedI have a large file (deflated size: 602191947)that is not saved in my Ubuntu One account. On sync'ing the file is being uploaded, and eventually reaches 602191947 - and then nothing more happens to this file - but sync'ing the following files in the queue goes on with success. I have tried manual upload with the same result. The file is still being marked as 'uploading' even after several tries and log ins/log outs, and reboots. So I was just wondering whether there is a file size limit - can't seem to find information regarding this.
View 5 Replies View Relateda possibly preposterous question. I am aware that you can designate a swap file or swap partition on your hard drive that linux uses as "memory". Suggested sizes for the swap file that I've seen range up to about 1024MB. Is there a limit to the swap file size that you can set?Basically I am running a perl script that processes a massive B) file (DNA sequence data), etc, and requires around 48 GB of memory to run, maybe a bit less. So, would it be possible to set a swap file to a massive, ridiculous size (~60GB oratever) and successfully run such a script on a desktop?Yes, I am aware that it would massively ow down the process. The thing is, if the perl script normally completes in about half an hour, and I can get it working on a desktop, I don't mind if it takes days or weeks to complete. I really don't. That's because it takes days or weeks to get access to a computer with the required grunt to do it.So, is this a stupid idea? Is it even possible? If so, given a perl script that normally completes in a half hour on a 48G system, if you do this, would it take days? weeks? decades

View 6 Replies View RelatedI want to generate core dump files from my program when it crashes. Its a pretty big process and has about 10-11 threads in it.I have followed the documentation to enable core dump by setting ulimit to unlimited etc. I quickly tried "A demo program creating a core dump" from the following webpage, which succeeds in Segfault and dumping a core file in the directory that I configured.However, I tried running my original program and caused it to crash. I did this by making calls to kill(), raise() or the same null pointer access as shown in the webpage above. In each case, my program crashed but did not generate a core dump file. Am I missing something?My program is in C++ and my environment is Redhat 9.0 (kernel 2.4.20)
Going through the "Why do I NOT get a core dump?" section on the same webpage as above, I can see two potential problems. One - there are issues with the suid/sgid (bullet # 6). I am not able to change any settings with suid because my system does not contain either /proc/sys/fs/suid_dumpable or /proc/sys/kernel/suid_dumpableTwo, my program has threads in it and the bullet # 8 is the problem.
I would like to build a NAS from PC (D510MO) running Debian. I have two HDDs (one 3.5 1T and one 2.5 500G).
On 3.5 HDD I have already two partitions 100M+40G dedicated for Win7-64. Now, I want to install Debian (second OS) on this PC and to have some kind of soft RAID or disk mirror of 500G space. I am planning to create a third partition on 3.5 HDD of 500G (identical as 2.5 HDD size) in order to have a mirror 500G space.
Please send my some suggestions on where I have to install Debian; on 500G 2.5HDD or 500G 3.5HDD!Will Debian boot from both HDDs 3.5 or 2.5 after I create the mirror? What Linux soft I have to use for mirroring (mdadm)?
Is there any Linux API that will let me control on what core will a thread run? If not, do I have to use assembly language?
View 2 Replies View RelatedI have recently merged two Joomla 1.0 sites I ran into one. I imported the articles I wanted to keep to the new site, and I have the old site's domain pointing as an alias at the new site. The new site is www.theouthousers.com . The old site was www.bludblood.com .
I also have the core SEF URLs on, using the htaccess.txt file that came with Joomla.
I have one writer for the old site who linked to his articles in various places, so I am trying to set up redirects for him so that he doesn't have to change all of his links.
For instance, I need something like:
http://www.bludblood.com/joomla/inde...d=25&Itemid=51
To redirect to the equivalent location on the new site:
[url]
And I also need specific links like:
[url]
To redirect to their new counterparts:
[url]
Keeping in mind that www.bludblood.com is now an alias of www.theouthousers.com, is there any way to do this? I have been trying with rewrite rules and redirects, and cannot seem to achieve the desired effect.
Tried various versions of:
Code:
Redirect [url] [url]
With the http, without, as regexps, as 301s, as permanents, etc, and it just will not work. Also tried as RewriteRule.
Assume someone bind a particular process to a particular CPU core(In multi core machine) by using sched_setaffinity() like functions. Then how we can get that process running core id and CPU core utilisation of that process on that running CPU core(Pragmatically or by a Linux command)?.

My pc becomes usable on a regular basis with minimum cpu usage because I can't open new applications There are no error messages etc, the new apps just don't open.
free -m shows the vast majority of my memory is used by cache
free -m
total used free shared buffers cached

I've done ...
echo 3 > /proc/sys/vm/drop_caches
Sometimes an app will open after this but the system becomes unstable, locking up regularly.
I not sure why the default max is 100% file cache but I'd to put a sane file cache limit in place, like 40% or something. I've put limits in place in the past using a percentage and I've poked arround but i don't see the setting.

(2) How do I limit each one of the folders ('folder1', 'folder2', ...., 'folder10') to a size of 100 [GB]? I don't want one folder (say, 'folder1') to grow in size and 'steal' the space designated to the other folders.
Does anyone know of a way of limiting a print-job size from samba?
I know how to limit a print job size form cups, and how to require x amount of free space before accepting a job. I've even dug up how to require x amount of free space for samba to accept a print job, but I can't see how to limit samba to only certain sized jobs.
Someone tried to print a >1G file to my print-server this morning, causing me to have a less relaxed Monday than I had hoped. Because it ran out of space before spooling, it was never limited by cups. Because I had to get rid of it ASAP so people could get work done, I have no idea who's it was, or where it came from. Scouring logs didn't give me any good leads either.
