    Description

      There is a test runner test which does repetitive creates and deletes and check to ensure that memory usage is constant and it is seeing memory usage increasing.

      Here is the command:

      python testrunner.py -i ~/servers/temp3.ini -t memorysanitytests.MemorySanity.repetitive_create_delete,items=200000,repetition_count=5
      

      And the error report is:

       
      2016-07-13 13:55:11 | INFO | MainProcess | test_thread | [basetestcase.sleep] sleep for 30 secs.  ...

      This is easily reproducible, logs are attached, please let me know if more information is needed.
