Load on Server Issue

Since the last update to WHM 64 I realize that the server has become very unstable, the load has gone up a lot, the sites are falling frequently. I would like to know what may be happening. I do not know if it's a problem with the new mod_security rules or the update itself.

  By doing the query with the following code the same returns me the list of connected IPS:
  netstat -anp |grep 'tcp\|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n
  The return shows more than 329 connections without IP and when this number exceeds 100 Apache stops working and the sites are down! What can it be? - Removed -
