Once it's been established (if it's established) that the process is getting oversized, you can sometimes see where the memory is going with: https://www.fugue.co/blog/diagnosing-and-fixing-memory-leaks-in-python.html But again, a memory leak isn't necessarily going to lead to a segfault. -- https://mail.python.org/mailman/listinfo/python-list
