memory-leaks

问题 I have a web application which uses Google's Datastore, and has been running out of memory after enough requests. I have narrowed this down to a Datastore query. A minimum PoC is provided below, a slightly longer version which includes memory measuring is on Github. from google.cloud import datastore from google.oauth2 import service_account def test_datastore(entity_type: str) -> list: creds = service_account.Credentials.from_service_account_file("/path/to/creds") client = datastore.Client

问题 The following minimal example of calling a python function from C++ has a memory leak on my system: script.py : import tensorflow def foo(param): return "something" main.cpp : #include "python3.5/Python.h" #include <iostream> #include <string> int main() { Py_Initialize(); PyRun_SimpleString("import sys"); PyRun_SimpleString("if not hasattr(sys,'argv'): sys.argv = ['']"); PyRun_SimpleString("sys.path.append('./')"); PyObject* moduleName = PyUnicode_FromString("script"); PyObject* pModule =

问题 I have a BaseActivity for all activities in my app. Here I create, add to the view hierarchy and load an AdView programmatically in onStart. If I navigate to other activity in my app and then go back, or exit app LeakCanary report a memory leak. In all the examples on the internet for Admob, the ad is loaded in onCreate, but we may use onStart see this and this There is more questions about this: SO, issue BUT NOT SOLUTION. The only solution that I found is to use onStart y onStop to use all

问题 I am working on an application that will be using Audio quite heavily and I am in the research stages of deciding whether to use Web Audio API on devices that can support it. I have put together a very simple test bed that loads an MP3 sprite file (~600kB in size), has a play and pause button and also a destroy button, which should in theory allow GC reclaim the memory used by the Web Audio API implementation. However, after loading and destroying ~5 times iOS crashes due to an out of memory

问题 I have a set of python processes that share a large object (sharing is done by forking the processes after initializing the object) I notice a strange memory leak: the process memory (VSZ and RSS) hardly change the total system memory increases steadily My guess is the shared object does change (it's 'logically' readonly, but it's possible that some internal private variables change even when just reading from it) - which causes memory pages to be copied is there a way to verify this? 回答1: To
