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
root@server [~]# vi /etc/init.d/httpd
Search for ulimit lines .For eg : you can see these lines
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 :
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 .
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.
