Django内存泄漏:可能的原因? [英] Django memory leak: possible causes?

问题描述

我有一个Django应用程序，每隔一段时间就会陷入内存泄漏.

I've a Django application that every so often is getting into memory leak.

我使用的不是大数据，可能会使内存超载，实际上，应用程序会逐渐消耗"内存(一周内内存从约70 MB变为4GB)，这就是为什么我怀疑垃圾收集器缺少某些内容的原因，但我不确定.而且，这种增加似乎与请求数无关.

I am not using large data that could overload the memory, in fact the application 'eats' memory incrementally (in a week the memory goes from ~ 70 MB to 4GB), that is why I suspect the garbage collector is missing something, I am not sure though. Also, it seems as this increment is not dependant of the number of requests.

明显的内容，例如DEBUG=True，保留打开的文件等...在这里不适用.

Obvious things like DEBUG=True, leaving open files, etc... no apply here.

我正在使用uWSGI 2.0.3(+ nginx)和Django 1.4.5

I'm using uWSGI 2.0.3 (+ nginx) and Django 1.4.5

我可以设置wsgi，以便在内存超过特定限制时重新启动服务器，但是我不愿意这样做，因为那实际上不是解决方案.

I could set up wsgi so that restart the server when the memory exceeds certain limit, but I wouldn't like to do that since that is not a solution really.

是否有众所周知的情况，垃圾收集器无法正常工作"?可以提供一些代码示例吗?

Are there any well know situations where the garbage collector "doesn't do its work properly"? Could it provide some code examples?

是否存在可能导致uWSGI + Django的任何配置?

Is there any configuration of uWSGI + Django that could cause this?
