We are seeing this using OpenJPA 2.1.0 in Oozie. A JDBCConfigurationImpl seems to be holding a large amount of memory via its dataCacheTimeout (then listeners) instance variable keeping
Class # Objects Used Heap Retained Heap ------------------------------------------------------------------- o.a.o.j.meta.MappingRepository 1,902 304,320 904,410,184 o.a.o.j.meta.ClassMapping 3,824 1,223,680 105,073,624 ------------------------------------------------------------------- We are using a single EntityManagerFactory and we are closing all EntityManager instances correctly (via a command pattern). All caching settings are default ones. Any hint where to look would be appreciated it. Thanks Alejandro
