While there are several ways to identify python memory leaks manually, it can be not easy to pick them up in a live application. On the other hand, you can not go about manually profiling each app to check if there’s a memory leak. That is why you need performance monitoring. ...

On examining the process memory usage, it continuously leaks, we are doing the following command to check(Note that the leak is slow and ultimately linux kernel oom kills the process.) while true; do ps -o pid,user,%mem,command ax | sort -b -k3 -r | grep <pid> ;date ; sleep 5...
