Working on program crash in linux with LKCD

[Aandaleeb]

I need some working information of LKCD. I have linux server in which my applications are crashed. It is possible to troubleshoot them via LKCD. But the same is not used before. Where to download it and how does it works in getting information on a crash program under linux based operating system.

The project LKCD is a set of Linux kernel patches and tools to save a copy of kernel memory when it panic. The kernel memory dump analysis allows after wards the cause of his panic. Thanks to the tools included in the package. Most commercial Unix systems come with similar tools.

On Linux, however, this package is fairly new and should be added manually. The utility LKCD is not intended to provide useful information in the case of a panic caused by a hardware problem or in violation of the memory segmentation. The complete package LKCD can be downloaded also from it's site. So that you will get more or additional information on it. And you can get rid of your problem.

The Working on program crash in linux with LKCD this only happen, when a kernel encounters certain errors it calls the panic which is produced by an irreversible mistake. In such a situation, LKCD carry a copy of the memory kernel to a pre-designated area. The area is the default swap partition primary (primary swap). Better collect more information on it.

The kernel is not fully functional at this stage, but there has sufficient capacity to copy memory to disk. When the copy is complete, the system restarts. When rebooting the system, if a new copy of the memory is found on the main swap partition, it is copied by default to the directory /var/log/dump Once the image is copied, the boot continues normally and forensic analysis can be done later.

There is a binary rpm package for i386 processors. It is available on lkcd.sourceforge.net. However, you still need the patches to be applied to startup scripts. You can find these patches in the source rpm package. Download lkcdutils-xxx.src.rpm and install it using the command: kcdutils xxx src.rpm. The download file of LKCD will place a file called lkcdutils- xxx .tar.gz in the directory /usr/src/redhat/SOURCES This file is an archive in tar format of the compressed source tree LKCD. Unzip the sources into the directory of your choice, eg /usr/src with the command: tar-zxvf xxx src.rpm. This will create a directory called kcdutils- xxx sources LKCD tools. In this way you can solve the problem of crash in linux with LKCD.
