Disabling the enable_crash_reports “fixed” the issue because it didn’t start the error_logger process.
error_logger is actually quite known to cause memory leaks 
There’s a whole section about this process in the Erlang in Anger book.
If I have some free time, I’ll try to fork Rollbax and replace error_logger with either logger or lager, because I would still like to have those crash reports.
