| Summary | 0043309: Memory leak in SBOImporterStore and SBOExporterStore | ||
| Revision | 2020-02-24 16:53 by caristu | ||
| Description | The SBOImporterStore is an @ApplicationScoped bean that centralizes the generation of SBOImporters. To do so, it has an injection to point to retrieve the SBOImporter beans (which are @Dependant scoped) and retrieves the correct instance depending on an Entity Mapping in particular (this is because currently we support two kind of mapping types: ManualBOB and RetailAPI) The problem is that all these created instances are living as long as the bean instance they are injected in is living. As the SBOImporterStore is @ApplicationScoped they are never being garbage collected which can eventually lead to OutOfMemory errors (see attached images with a memory dump of an environment affected by this issue). This very same problem also happens with the SBOExporterStore. See here[1] for a more detailed explanation regarding this problem.
