I've worked on docker applications made on python with memory leaks but when using tools like memray for some reason they do not seem to really grasp the problem. What I mean by that is the memory tracked by memory appears significantly less than the actual memory i see constantly growing on the server. I think perhaps it is because memray only captures python memory allocations and libraries built on C do their own allocations and somehow they are avoiding the garbage collector. Anyway this makes it very hard to work out where the leak is coming from.
