Assistance needed with WHMCS account causing WHM Load Issues

We just installed a ModuleGarden Multibrand module on our WHMCS installation, and we migrated 4 WHMCS accounts from another WHMCS install. Both actions were normal - nothing out of the ordinary. However - after those 2 actions, our server load has spiked majorly. Here's some of the entries in our process log that are using up a log of CPU. /usr/bin/php /home/accountname/public_html/clients/admin/[login to view URL] /usr/local/apache/bin/httpd -k start -DSSL /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/[login to view URL] --open-files-limit=50000 --pid-file=/var/lib/mysql/[login to view URL] Those 3 errors above are the most common - and obviously related to the actions we took. We need someone who can troubleshoot this and help us fix this load issue. It's got to be some repetitive error - we don't get enough traffic to trigger this kind of load.
