Out of Memory - Slow leak?

This is a continutaion of Issue 61 - unfortunately it doesnt seem that the fix in 2.2.9_03 has fixed the problem. The scenario is still the same: I have two "producer" processes which insert messages into an objectdb "queue" database running with an objectdb server process. I have one "consumer" process which reads messages from the queue database and inserts these into an embedded "normal" objectdb database. This is the process which has generated the OOM exception.

problem with lazy loading - unittest project attached

hi, i'm still testing objectdb together with spring-data-jpa. i made a test which should simulate 4 requests 1. save entity 2. read an existing entity, add onetomany relation 3. read an existing entity, add another onetomany relation 4. read entity, get relations. i have the feeling this is not the optional way to test this, because of the differnt transaction behavior. the test is not transactional, but the spring repository methods are. #1 2011-05-04 05:32 hi, i'm still testing objectdb together with spring-data-jpa. i made a test which should simu ...
