This is concurrent connections to apache, SSH and Cron Jobs, this means at that time you had 14 concurrent connections using one of these services. If you have shell access you can see currently running processes for your user by running something like:

Code:
ps faux |grep username
Because this is typically php-cgi usage you might check the error log in cPanel>>Metrics>>Errors to see if potentially you have scripts that are misbehaving. You can see your traffic in metrics as well.

The description of EP from CloudLinux is also informative:

Entry processes
Entry processes limit controls the number of entries into LVE. Each time a process 'enters' into LVE, we increment the counter. Each time process exits LVE, we decrement the counter. We don't count processes that are created inside LVE itself. It is also know as 'Apache concurrent connections' limit.

The process enter's into LVE when there is a new HTTP request for CGI/PHP.

This limit was created to prevent DoS attacks against web server. One of the fairly popular attacks is to tie up all the Apache connections by hitting some slow page on a server. Once all Apache slots are used up, no one else will be able to connect to the web server, causing it to appear to be down. The issue is worsened by CPU limits, as once site starts to get slow due to CPU limit – it will respond to requests slower and slower, causing more and more connections to be tied up.

To solve that, we have created entry processes (often called concurrent connections) limit. It will limit the number of concurrent connections to Apache, causing web server to serve error 508 page ( Resource Limit Reached), once there number of concurrent requests for the site goes above the limit.
