Hi, I like to compute differences between two snapshots (diff), rather than looking at a single snapshot: https://docs.python.org/dev/library/tracemalloc.html#compute-differences
You can modify your signal handler to write the snapshot into a file using pickle.dump(): https://github.com/vstinner/tracemallocqt#usage Then use pickle.load() to reload snapshots from files. You can take multiple snapshots and compare snapshot 1 with snapshot 2, compare 1 with 3, etc. If there is a major memory increase between two snapshots, I expect a significant difference between these two snapshots. You can configure tracemalloc to decide how many frames per traceback are stored. See -X tracemalloc=NFRAME, PYTHONTRACEMALLOC=NFRAME and start() argument: https://docs.python.org/dev/library/tracemalloc.html#tracemalloc.start tracemalloc only "sees" memory allocations made by Python. You can get the "current size size of memory blocks traced by the tracemalloc module" with: https://docs.python.org/dev/library/tracemalloc.html#tracemalloc.get_traced_memory Note: tracemalloc itself consumes a lot of memory, which can explain why your application uses more RSS memory when tracemalloc is used. If there is a huge difference between the RSS memory increase the what tracemalloc see (ex: RSS: +100 MB, tracemalloc: +1 MB), maybe you should use another tool working at the malloc/free level, like Valgrind.
