Oh yeah, Gabriel, another technique you can use is to start your app and create a memgraph _before_ reproducing the problem. Then reproduce the problem and run ‘heap MyApp --diffFrom MyApp.memgraph’. It will show the new objects that have been created since the memgraph was taken, sorted number of objects. That might narrow down what object(s) are eating your memory. Good luck.
