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:

Code:
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?

Hello,

The following thread is a good place to start when troubleshooting high resource usage:

Troubleshooting high server loads on Linux servers

As far as the Apache issue, do you notice any specific output to /usr/local/apache/logs/error_log when Apache stops responding?

Thank you.
