Connection is closed Caused by: java.io.EOFException

I am getting this exception on a regular basis, after a period of time of repeating the same code execution.  I don't understand why.  I restart the DB server and my code works again for another period of time until same exception is encountered again.  I cannot pin down a pattern e.g. after a certain period of time,  because the time  periods between exceptions are not regular, although frequent.  Any test case  I use will pass most of the time but will fail after an undetermined period. ... initial = "256kb" resize = "256kb" page = "2kb" /> <recovery enabled = "true" sync = ...

How to track memory leak with ObjectDb.

Hello, I suspect some memory leak in my application. ( turning app into OOM very fast ) In fact, some com.objectdb.o.MST objects are retaining a huge % of my heap space. While watching the dump file ( with Eclipse MAT ), i was not able to inspect carrefully the memory leak issue. That's is very hard to debug because of obfuscated objectdb code. Well, objectdb is closed source, ok so ... but, in production case, how can a developper do his debug job correctly with your obfuscated code ? ... 22:31 This shows the page cache.
