It looks like your server ran out of Heap space. You can increase the heap size to fix the issue but I would strongly recommend you read this threads

Hello. I am having similar issue with Jasper Report Server - java.lang.OutOfMemoryError: Java heap space, on upgrading to Jasper Report 6.5.1.This is making the application completely unresponsive.

The issue occurs at multiple locations and logs provided below. I have set the JVM Heap space to 8GB, but still does not help. Please let me know if you have any solutions. Thanks in advance.
