Hi All

I have used Eclipse Memory Analyser to analyse the Heap Dumps of my Spring MVC application. It shows there is a potential memory leak with the Spring SessionFactoryImpl, I am unable to figure out what exactly is causing this issue.

I am attaching the screen shots here of the complete memory analyser.

Kindly request someone to please help me.

As seen on page 22, 50 of 78 MB is consumed by QueryPlanCache.

So you need something like https://stackoverflow.com/questions/31557076/spring-hibernate-query-plan-cache-memory-usage

On the other hand, the memory consumption is just 50M, so you might want just increase the heap size and see how it would go.

Hi

Thanks a lot for the help. As mentioned I would like to increase the HEAP size and see if it all goes well.

Also please let me know what exactly is causing the WebClasscloader to occupy 40M, could you please let me know how to trace the HashMap and find out what are the objects holding back in memory and why this HashMap is occupying 40M memory.

Please find the screen shot attached.

Thanks,
-Hari.
