Index causes increased memory usage
Hello, ... noted that our database application is consuming MUCH more memory (~8gb instead of ~3gb) than when the indices are not included. What could be taking up that memory? The data load was the same for both tests (with and without ...

Suspected memory leak
Hi, We are running soak testing with Object DB and it is showing signs of memory leak: used memory is growing overtime until Object DB JVM fails with OutOfMemoryException. Object DB is running in a separate JVM. All the config is attached. We are continuing to investigate this and will create memory dump next time this happens. In the meantime, could you please check if there is anything wrong with our configuration? Kind regards, Natalia. ... soak testing with Object DB and it is showing signs of memory leak: used memory is growing overtime until Object DB JVM fails with OutOfMemoryException. ...
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. ... I've attached the leak suspects report from Eclipse Memory Manager in the hope it may help. Please let me know if you need ...

Large query parameter - out of memory
I have an entity object composed of an id, large data in the form of a string and the hashcode of the string as an index. The attached test saves 2000 of these objects, writing the data to a txt file as it goes. It then loops through the data from the file and queries for the entity id based on the data hashcode and the data itself. ... the id. After about 300 queries the test throws an out of memory exception so I assume the query data is being held internally. I've ... cache to prevent the need for large data to be held in memory.

Doctor - high memory usage
Hi, Is it possible to reduce Doctor memory usage? Right now for recovering 67MB database, I need to set heap space to at least 450MB. Even then whole process takes ages. Optimal setting for this database is about 650MB. It's about ten times of size of database. ... Hi, Is it possible to reduce Doctor memory usage?

Sort of very large objects - out of memory
The attached test is failing with an out of memory exception when running with -Xmx512m It performs the following actions: 1) Create 5 persist threads which create and persist a large object in a loop 100 times each 2) Create 5 get threads which read 100 objects each in a loop based on object creation time and priority The message size should be around 1mb so I think there should be around 11mb of "live" data in play at any time. The objectdb cache settings are low in the config - database section is below for reference. ...
