I checked my error log and it's filled with this SoftException in Application.cpp:641 with a link to my public_html index.php file, similar to what you see in the screenshot concerning processes. A google search showed this error message is prevalent in HostGator accounts and other people were also noticing their processes maxing out and thus, Internal 500 server errors. Why that is the case and why that's in the error logs is another part of the mystery.
