OpenDaylight Yang Parser & YangTextSchemaSourceSetCache
It was previously suspected that the 3rd party OpenDaylight Yang Parser may have a memory leak. See comments on CPS-2000:

While CPS has a cache called YangTextSchemaSourceSetCache to avoid invoking the OpenDaylight Yang Parser, the Yang Parser's internal cache may be causing a memory leak. This requires immediate investigation.
Hazelcast
The use of Hazelcast (an In-Memory Data Grid) has been identified as a particular source of high memory usage. Some points of interest:
