Hi matplotlib developers and users,
I have had some problems with a memory leak in a long running
matplotlib based web application that I have developed
(www.worldwildweather.com). I believe the problem is due to a memory
leak in the Agg backend but I am not sure. Below is a script which for
me re
Hi all,
a few hours ago I have wtitten for a possible memory leak in Agg backend.
It was my fault. It was a bad placement of matplotlibrc file.
Sorry for the raised alarm.
Instead i am glad to say that I have checked for the Agg backend with a for
statement of opening a figure, drawing, saving and

Well, in my setup I see similar behaviour as in the initial question.
Ubuntu 8.10 32bit,
Are you able to run it inside of valgrind's massif tool? Calling out to
ps can be a bit spurious (particularly with a memory-pooling Python
build) especially for a leak this small.

Well, I have never used it before but here is the output from valgrind
masstif, can you figure out something from this? The mem usage from
python was still increasing.

Hi Michael and others,
Sorry for the late answer. I am on Ubuntu 8.10. Unfortunately I have
not had time to look any more into the issue (which might very well be
an error on my part) but I will return when I have more info (I have
made a temporary fix).
I tried using valgrind-massif to reproduce
I forgot to mention that it seems like the issue is related to the
Figure object (and not any foreign language extensions?). When a
fig.clf() is added before the call to report_memory the memory usage
is constant. Since I am reusing the Figure instance this is a problem
for me. But maybe I just nee
