Udo Kohlmeyer commented on GEODE-1146:
--------------------------------------

this issue can be reproduced by running the test often. GC then kicks in and causes the issue.
This flaky behaviour should be fixed once the VMs are bounced. 

In a test I ran the test 80 times which caused a GC and then test failure. When I introduced the capability to bounce the VM every 30 tests, the GC problem disappeared and this test ran over 3hrs (over 3500 iterations) without failure until I stopped it.
