Re: [libvirt] [libvirt-users] JVM crashes during GC

Hi, Could you tell me if the following is some known issue? While performing the following simple test, I see my JVM crashing (consistently): 1. Open a connection to an ESXi driver/host (passing ConnectAuthDefault instance). 2. Close the connection. 3. Invoke GC When GC is triggered, at some point, some unallocated native memory is being tried to release. That's failing. The error thrown is: java(78745,0x70000241e000) malloc: *** error for object 0x7fd5df561390: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug Frames from core dump: frame #0: 0x00007fff5b274b66 libsystem_kernel.dylib`__pthread_kill + 10 frame #1: 0x00007fff5b43f080 libsystem_pthread.dylib`pthread_kill + 333 frame #2: 0x00007fff5b1d01ae libsystem_c.dylib`abort + 127 frame #3: 0x00007fff5b2ce8a6 libsystem_malloc.dylib`free + 521 frame #4: 0x00000001127f43a7 frame #5: 0x00000001127e3ffd frame #6: 0x00000001127e3ffd frame #7: 0x00000001127e3ffd frame #8: 0x00000001127e3ffd frame #9: 0x00000001127e4042 frame #10: 0x00000001127e3ffd frame #11: 0x00000001127e3ffd frame #12: 0x00000001127dc4e7 frame #13: 0x000000010c0e235e libjvm.dylib`JavaCalls::call_helper(JavaValue*, methodHandle*, JavaCallArguments*, Thread*) + 1710 frame #14: 0x000000010c0e2b02 libjvm.dylib`JavaCalls::call_virtual(JavaValue*, KlassHandle, Symbol*, Symbol*, JavaCallArguments*, Thread*) + 356 frame #15: 0x000000010c0e2cae libjvm.dylib`JavaCalls::call_virtual(JavaValue*, Handle, KlassHandle, Symbol*, Symbol*, Thread*) + 74 frame #16: 0x000000010c1208ee libjvm.dylib`thread_entry(JavaThread*, Thread*) + 124 frame #17: 0x000000010c33e84d libjvm.dylib`JavaThread::thread_main_inner() + 155 frame #18: 0x000000010c33ff12 libjvm.dylib`JavaThread::run() + 448 frame #19: 0x000000010c26058a libjvm.dylib`java_start(Thread*) + 246 frame #20: 0x00007fff5b43c661 libsystem_pthread.dylib`_pthread_body + 340 frame #21: 0x00007fff5b43c50d libsystem_pthread.dylib`_pthread_start + 377 frame #22: 0x00007fff5b43bbf9 libsystem_pthread.dylib`thread_start + 13 I have installed Libvirt 5.2.0.
