   @aravindhv10 
   I was able to run your program.cpp under valgrind.  I did not notice any memory leak in "Backward()" call.
   I also tried to monitor the RSS consumption and it was very steady after the initial epochs.
   The RSS consumption also went down after invoking "MXNotifyShutdown()".
   
   There was recent PR merged to fix the potential memory leak https://github.com/apache/incubator-mxnet/pull/14223/files#diff-1857b9d275cb36ebeafadf72a278d09aR81
   
   Can you please try running the test again?
   
   I did notice that the Optimizer object ("adam") created in program.cpp is not getting freed.  But that is one time allocation and does not increase overtime.
