Hi again, You should do a jvm memory dump using a tool like visualvm.
Using windows task manager won't give you meaningfull info. All you will see from the task manager is that the memory allocated to the jvm process increase until max size and is never freed until jvm stop : this is the normal behaviour of the jvm. By default jvm never gives back to the os the memory that was allocated : is does not mean there is a leak, as long as the jvm heap does not grow indefinitly.
