It looks as if your GC (Garbage Collection) is the issue. I recommend looking over this doc to see if it might help you remediate the problem: https://docs.appdynamics.com/display/PRO43/Garbage+Collection
Newer version of the above Appd Docs page: https://docs.appdynamics.com/display/PRO45/Garbage+Collection#space-menu-link-content
This is also a good resource: http://www.baeldung.com/java-gc-overhead-limit-exceeded
