Server :: How To Create Kernel Dump On RHEL 4.7
Jan 11, 2011My application team is asking me to generate the kernel-dump.
Here are details about my server.
OS: RHEL 4.7/32 Bit
Kernel Version: 2.6.9-89.0.23.ELsmp
Processor: Intel(R) Xeon(R) CPU E5520@ 2.27GHz
Hardware: HP Proliant 380G6 series server.
I am using Electric Cloud applications. Sometimes it creates some kernel panic and immediately got rebooted. Kernel-debuginfo rpm is not installed. In some thread, I read the kernel-debuginfo rpm's version should match with the kernel version. In my case I couldn't even find the exact version of kernel-debuginfo version.

Programming :: Core Dump Issues. Program Crashes But Does Not Generate Core Dump File?
Oct 7, 2009I 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.

View 2 Replies View RelatedServer :: Disk Dump - Creating Virtual Directory
Apr 14, 2010I'm quite new to linux, but I've managed to grasp some basics. Now my intention here to create a virtual directory, which I resorted to creating an Image File so that I can mount it and have my folder have a dedicated storage. I will mount this image as a loop device. Well it's not much of a problem, but I would like to know whether this is suitable. Say I want to create a 25GB Image.
Code:
dd if=/dev/zero of=/home/disk-img/25GB.ext3 bs=1G count=25
Is this recommended? I'm using block size as 1G which is really huge, so I was wondering, if this is actually recommended. From what I read, some said that it's only advisable to use 4096k or lower, but what I found was that these suggestions are very dated (year 2003), and it is now 2010, so I would like to know if it makes any big differences.
Server :: Create Core Dump When My Application Crashes?
Dec 29, 2010I am using RHEL 4.7 (32bit) on HP Proliant 380G6 series server. We are using Electric Cloud Agents on these servers. Nowadays we are facing some memory issues and its creates some kernel panic and then restarts the server. When i reported the issue to my application team, they asked me to come with the core dump. I googled it enough, then i set ulimit value as unlimited. (previously it was 0, then i made a entry in /etc/profile file as follows
ulimit -c unlimited) But still whenever my server restarts due to that kernel panic, it couldnt generate the core dump. My application was installed on /opt
The attached document has the kernel panic logs
Server :: Dump All Users To The Same Sftp Starting Directory?
Jul 7, 2010Using CentOS 5.5. I have a handful of users that I need to have connect to my server via sftp and start in the same directory. for example, user1, user2, user3, etc.. will connect via sftp and upon connection will all be in the /some/dir/path/ftp-root directory.I know one way is to create these users all with the same 'home' directory, since by default a user starts in their home directory when connecting via sftp, but before just doing that, I wanted to find out if that is really the appropriate method to use? alternatives? Is there some setting on the sftp server end that could direct all users to one starting directory so that these users don't have to have the same 'home' dir? I'm using the sshd daemon that comes with CentOS 5.5 (with all current updates/patches)

OpenSUSE Install :: Windows Always Stores Its Boot Detail In MBR
Oct 8, 2010I have decided to jump from windows to Opensuse and experince more of an Linux world. Windows always stores its boot detail in MBR similarly for Linux too but i have learnt that in many different installation of Linux that we can store in the first part of the Partition but trying out i have always failed to start, since the MBR fails to identify it. I have also tried EasyBCD and adding the link to Grub as the first partition but that too it din't work.
Question 1: i hate to writing multiple times on my MBR.
Question 2 Also let say due to some reason if i have to reinstall my windows the GRUB get lost. How can i restore back.

Mar 10, 2010Normally to find out some info on a package we have installed on our system, i pop open a shell window and execute: yum info <packagename> and this returns a lot of useful info (in this example, lets consider GIT) about statistics on currently released packages:

obviously using a few commands at the shell is a little bit easier than this, but some users may be using software without ssh access enabled.

However, is there a way to do 'yum info' like commands via the web browser on packages that are released but that we haven't yet installed or updated to? Or even on packages in other repositories (RPMForge, CentOSPlus) without having to configure our version of YUM in include those repositories so we can query them? I guess in the debian-sphere, the way i used to do stuff like this was via their website. Like for git, i did:[URL]
Red Hat / Fedora :: Increase Detail Of Messages Logfile To Help Resolve A Intermittent Crash?
Mar 29, 2010My server is running Red Hat 4.1.2-44.I am having an issue with it hanging (website doesn't respond, can't connect via SSH (it's a remote server)) after 4am on every 3rd Sunday or so.A reboot is required to get the server responding again.I have checked every logfile I can find and found nothing that helps me. The thing I have noticed is that some of these log files start afresh after the reboot so my initial thoughts are that it is a logrotate issue or something similar.
The last activity I can find before the reboot (at 8:32) is in the logfile /var/log/cron:
Mar 28 04:22:01 crond[9356]: (root) CMD (run-parts /etc/cron.weekly)
Mar 29 08:32:39 crond[3884]: (CRON) STARTUP (V5.0)

For some java processes, I didn't find any details in the /proc/<java pid>/statm file. It has only 7 number of 0s. But /proc/<java pid>/stat file has the details. And also this kind of process will have the life time of nearly 1 minute.
