You may come across core files which gets generated within your accounts . 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. Following are the steps to edit httpd startup file.
root@server [~]#which httpd
/usr/sbin/httpd
root@server [~]# nano /usr/sbin/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 [~] /etc/init.d/httpd restart
