hello @zhengwei14, a few questions on your setup. are you running on the master branch? what version of PMDK do you have installed? do the LLPL tests run successfully? you can run the testsuite via "mvn test -Dtest.heap.path="

java version "1.8.0_60" Java(TM) SE Runtime Environment (build 1.8.0_60-b27) Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

LLPL:1.1.0 release

PMDK:1.9.2

I create thousands of heaps and blocks, then JVM crashed.
by the way, why the heap.close() and Heap.deleteHeap() isn't Declared public. I can't close heap.

I used reflection to invoke the AnyHeap.close(), then it runs successfully。
