Apache killing my system

So apache is creating so many processes of itself that its making my server completely time out.
I have tried remaking all accounts, rebuilding apache and php-fpm but nothing fixes it.
What should I do?

Hi, you have to find the reason. Probably a website has DDoS attack

You should use ps -aux | grep apache to find out the number of processes that apache is running on. And lookout for the "RSS" column which gives an estimate of the memory used by each process. Alternatively, you can use "top", where you shift + f and then select the %MEM column to sort the processes by memory usage.
