Alfresco Activiti Memory Leak

Question

Thanks in advance for the help.

I'm having this issue with Alfresco Process Service where the memory is reaching the JVM limit, CPU is usually below 10%. Usually happening quicker when we make requests to the endpoint (/activiti-app/api/enterprise/tasks/query). Just wondering has anyone seen this issue before?

Config: -Xms8g -Xmx16g

Heap dump:

1 instance org.hibernate.engine.internal.StatefulPersistenceContext  Retained Size 10.660 MB (97%) 
    1 instance of org.hibernate.engine.internal.EntityEntryContext 10.656 MB (100%) 
        67231 instances of org.hibernate.engine.internal.EntityEntryContext$ManagedEntityImpl 10.655 MB (99.9%) 
             67231 instances of org.hibernate.engine.spi.EntityEntry 10.653 MB (99.9%)
                67230 instances of java.lang.Object[] 10.648 MB (99.9%)
                    67230 instances of byte[] 10.609 MB (99.5%)

Endpoint: /activiti-app/api/enterprise/tasks/query Request Body: { "appDefinitionId": null, "sort": "created-desc", "size": 50, "start": 0, "text": "", "state": "completed" }
