Core dump files

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

If it is caused due to php/apache then you can get rid off those core files by editing the httpd start up file on the server end.
To Disable creation of core dump files:
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

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
