Stop Coredump file

  • Many webmasters ask me how to stop core dump files in Apache.. Now today i will tell you how to stop core dump file in apache.  This is basically happens when System Crashes it makes a coredump file in the public_html Directory.

    The possible reason for the core files getting generated is when a php process is killed, apache creates core files under your account .

    On phpSuexec servers this may cause due to incorrect php.ini file placed in your account and if it is caused due to php/apache then you can get rid off those core files by editing the httpd startup file on the server end .

    Lets start

    Code:
    root@server [~]# vi /etc/init.d/httpd

    Search for ulimit lines .For eg : you can see these lines

    Code:
    ulimit -n 1024
    ulimit -n 4096
    ulimit -n 8192
    ulimit -n 16384

    You need to add ulimit -c 0 at the end .Which will look like :

    Code:
    ulimit -n 1024
    ulimit -n 4096
    ulimit -n 8192
    ulimit -n 16384
    ulimit -c 0

    root@server [~]# :wq

    Save changes and quit.
    Now kill / stop apache service and then start apache service on the server .

    Code:
    root@server [~]# service httpd stop
    root@server [~]# service httpd stop
    httpd (no pid file) not running
    root@server [~]# service httpd startssl
    root@server [~]# service httpd startssl
    httpd (pid 21154) already running

    Finished :D

    It works most of the OS.

    Self tested on CENTOS 5.2 i686 on standard

    The “Coredump” project is a web-controlled physical machine built by Garnet Hertz between 1997 and 2000 that allows users around the world to remotely control a markmaking robot via a computer over the internet. Instead of the traditional dumping of memory from a malfunctioning computer program, it attempts to take random bits from users over the internet and dump them into physical space.

    Do I need to attach them with credit card statement ? And do I need to file them separatly with other invoices. Or I can just file them the same way as I file the other invoices that are not purchased by credit card? And how do I file receipts that are purchased by petty cash? Do I need to file them separatly?

    We tend to not think about improvement things if everything is working fine. If it’s working, don’t fix it. Now this is a wrong practice. This is why maintenance is very important, and removing or stopping core dump file is one of the things we can do to maintain our systems.
