|
|Hey Everyone,
|
|I just upgraded to Beta-Prod 3 and still having Out of memory exceptions on
|the server side. To test to see if I didn't have memory leaks in my own
|beans, I completely scraped those and created a dummy Entity Bean
|- attached
|below - Using BMP but just ignoring the ejbSaves / ejbCreate and not
|persisting anything. If I create upwards of 150,000 objects from clients
|and I get OOM on the server i.e.:
|
|[TestingHome] --Create--167657
|[TestingHome] TRANSACTION ROLLBACK EXCEPTION:null; nested exception is:
| java.lang.OutOfMemoryError
|[TestingHome] java.lang.OutOfMemoryError
|[TestingHome] <<no stack trace available>>
|
|
|
|My bean has a sample main client build in so you can see what I am doing...
|Is there a setting somewhere on the max number of cached objects???
