It turns out that the requests with high ram requirements are so well distributed that I'm not running out of memory. So my initial concerns (the first mail in this thread) can be forgotten. YAY. -Andrin On Wed, Feb 22, 2012 at 9:08 AM, Robert Kluin wrote: > Hey Alex, > I should probably have

Hey Alex, I should probably have stated this better as memory is not always handled well. For example, the ext.db code keeps many copies of the data in various forms. This can cause rapid and unexpected memory blowups, and the result is something that appears similar to a memory leak. As Brian

The whole point of this topic was python27 runtime, multithreading and concurrent requests. Your specific case, plus python 2.5, doesn't necessarily means memory leaks in the runtime itself. I'd profile my code that handles most frequently accessed URLs to start off. -- You received this messa

I would love to learn more from google on python memory handling. As Robert mentioned, we have observed that memory is not released/garbage collected on python 2.5 instances. It seems to just hold on to it. This works because the instances don't live forever and eventually get shutdown and new o
