   @zachgk  Sorry for the late response, I had to find some time to run through my tests.
   
   I modified my repo (https://github.com/jessebrizzi/MXNet-Bug) with the example code for the memory leak bug to use the snapshots published in the Nightly Repo https://repository.apache.org/#nexus-search;gav~org.apache.mxnet
   and include a Dockerfile that sets up an image to test my code with the nightly builds (You have to change the Cuda version in the docker image to switch between `1.4.0-SNAPSHOT` and `1.5.0-SNAPSHOT`)
   
   I think I am still seeing the bug (native memory climbing when jvm and gpu memory stays stable), but I am running into a crashing issue when running my "bugged" repoduction code https://github.com/jessebrizzi/MXNet-Bug/blob/master/scala/TestBug.scala
   
   In CPU mode the script will freeze after a few hundred loops with all CPU's pegged and in GPU mode it freezes with the GPU/CPU idling.
   
   In the non-bugged version (https://github.com/jessebrizzi/MXNet-Bug/blob/master/scala/TestNoBug.scala) of my repoduction code this does not happen, it runs fine since it avoids the resize call.
   
   I'm currently trying to get a repo/test using the current 1.3.1 published release, but I have to work through some other blocking issues with that (Mainly the 1.3.1 published scala jar for Linux-GPU is built against opencv 3.4 instead of the opencv 2.4 provided by Ubuntu 16.04 https://packages.ubuntu.com/xenial/libopencv-dev), and I'll comment again when I have that working.
