Issue/Introduction

We have a user who is running a test with a custom logging .jar.  We have run the test with Simulator Heap Sizes of 256mb min - 20gb max.  Then, we increased to 4gb min - 40gb max and it still consumed 75% of heap memory and would not let it go. The final test was when we set the heap to 150gb min - 200gb max. It actually consumed 50% of the memory of that and did not let it go at the conclusion of the test. When we do not use the custom logging .jar, we do not see the consumption issue...everything works fine.  I have attached the tmp folder logs from both the reg coordinator server and the simulator. I see in the coordinator.log a lot of the messages below. You can see them all in the logs. I have also attached the custom logging .jar.
