You need to diagnosis the jvm usages like how many process is running and what about heap allocation. there exists a lot of ways to do that for example

• you can use java jcmd to check number of object, size of memory (for linux you can use for example "/usr/jdk1.8.0_25/bin/jcmd 19628 GC.class_histogram > /tmp/19628_ClassHistogram_1.txt", here 19628 is the running application process id). You can easily check if any strong reference exists in your code or else.
