Hosting suspended due to CPU usage, Question

I am looking into if there is something abnormal using my cPanel server CPU

I am just about to fix this bug: PHP Fatal error: Class 'productPricing' not found in /home/jbmminia/public_html/zencart151/includes/init_includes/init_currencies.php on line 47
But I don't think thats a problem.

I will be optimizing the site for CPU but wonder if there was something abnormal that may have caused this.

Letter from Hostgator:

HostGator:

Hello,

Your account has been abusing CPU resources for an extended period of time.
As a result all of your sites have been cached in order to ensure continued
performance stability of the server. While we do limit each account to no
more than 25% of a system's CPU in our terms of service, we do not actively
take actions against accounts until they greatly exceed that number, which
is what happened in this case.

Please take a moment to review this email in full as it contains important
information and resources to assist you in resolving this issue. Please note
that this permanent restriction requires you take further actions to gain
access to and resolve the issues on your account.

Please note your site(s) are still online in a cached form. However, any
further violations will result in your account being suspended

• Important information on the caching for your account
  Your account will be cached for 12 hours, with the cache for your sites
  updating every 3 hours. This will allow your site to stay online for
  visitors while you correct the issues causing the problems described below.

Once your sites are fix and no longer causing service issues and remains
incident free for 12 hours the restrictions will be removed and your account
will function normally.

• How can you resolve the issue?
  We have two solutions available. You may try following some of our tutorials
  for optimizing popular scripts.
  http://support.hostgator.com/articles/specialized-help/technical/optimize-cpu-resource-usage.
  If you feel your scripts have already been optimized, it may simply be time
  to consider the hardware upgrade. Moving the account to a dedicated server
  will allow far greater hardware resources and dedicated hardware for your
  account.

• How does a CPU issue occur?
  Many times popular scripts may perform inefficient tasks repeatedly leading
  to CPU abuse. Below please find helpful articles outlining resource
  restrictions set on HostGator accounts:

  https://support.hostgator.com/articles/pre-sales-policies/rules-terms-of-service/cpu-resource-usage

• What is caching?
  Caching allows us to server a static page taken of your site. Each
  subsequent page request is then served from the cache. This allows us to
  reduce server load, bandwidth usage, and maintain server performance for our
  other customers.

Many customers opt to cache certain parts of their websites to ensure
optimal performance for their sites. Below are links to optimizations guides
for popular CMS's.

Treat it as though the site's been hacked until you've done a thorough inspection of everything to prove otherwise:
http://www.zen-cart.com/wiki/index.php/Recovering_From_Hacks

And, I'd make a point of downloading a complete copy of all files from your site ASAP ... both for backup purposes and to use in the inspection process.

Not the problem you are looking for but it probably should be looked at

you appear to be trying to use a PDF as an image

<div id="bannerSix" class="banners"><img src="images/small furniture catalog.pdf" alt="Download a Copy of our New 1:24 Scale Catalogue" title=" Download a Copy of our New 1:24 Scale Catalogue " width="140" height="114" /></div>

I believe the problem turned out to be easy populate had an error and created thousands of duplicate sub categories, when a customer went to the parent or sub category having such large number of categories caused some kind of higher CPU usage. At lease when easy populate was used again it updated the categories correctly and our host said the CPU usage was fine.
