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
It works most of the OS.

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.
