It looks like one hour later, one minor GC can only collect little die objects in survivor space, there are many objects are survivoring.
Then in the next minor GC time, lived objects fills up in the survivor space, any remaing live objects will copy to tenured generarion.
But what make me adoubt as why one hour later, the objects become difficult to release...
Can somebody help me to find out the problem with me?
Thanks!
