I also have the same experience.
Following steps were always escaped from my BO crisis.

1.  Search for unusual extensive access.
         tail  -200  /var/log/secure

2.  If you find the IP address,   DROP it on you server.
         /sbin/iptables  -A  INPUT  -s  xxx.xxx.xxx.xxx -j DROP

3.  Using a TOP command,  Obtain the IDs of invalid new processes.
     Then,  KILL new processes.
         kill  -9   xxxx xxxx xxxx xxxx xxxx ..............
