matplotlib pyplot stop working

[dk]

I am using matplotlib.pyplot to generate a plot image, put it in a temp folder,

and then use that to populate a webpage.

the problem is:

1) always display the same image,  I all ready deleted the image before creating the new one,

I also set pyplot .close()  to close all my figures.

2) some times everything freeze and stop working.

my suspicions is since django is constantly running keeps the figure in the memory some how.   have any one got issues like this?

thanks.

Hi,

The freezing could be a memory leak. http://stackoverflow.com/questions/7125710/matplotlib-errors-result-in-a-memory-leak-how-can-i-free-up-that-memory

Could the image be cached by the browser, does shift+F5 refresh it? The easiest way to fix it would be to use a different url/filename every time you generate an new image.
