   > I asked the infrastructure team how much memory we can use: https://issues.apache.org/jira/browse/INFRA-21207
   
   Thanks @aajisaka ! 
   
   > It would be nice to know what's tying up all of our memory. Because 20 GB is a lot for us to be using for unit tests
   
   @ericbadger . Definitely!
   It would be easier to narrow the scope of investigation if we had this error reported the earliest it started to happen.
   Unfortunately, it does not seem that it is the case.
   The other way is to profile the memory of the image during the execution. Do you have any suggestion of how to approach this?
   A straightforward way would be to dump the system men to the log at the beginning of each module.
