[mathieu@newview.com: X Window resource leakage]

[Richard Stallman]

Could someone please investigate this?  I don't know if this is a bug
or if nobody has ever written code to free the images in the X server.
It would seem like a good idea to free any image that has not
been displayed in some period of time (10 minutes) and which is
not currently on the screen.

Hi all,

I've been using emacs and gnus for quite some time and I'm puzzled by a
problem I'm having. I don't really know if it's an emacs or gnus bug but
I'm posting this message here for now.
I use emacs 21.3.1 and gnus to read usenet and I'm also subscribed to some
binaries newsgroups (mainly plane stuff).
When emacs opens a message that as image embedded in that it's able to
display (more on that later), it displays it. So far so good, except that
it allocates some memory and never frees anything.
I have tried the cvs version of yesterday (21.3.50.2) and the same thing
happens. If you don't restart emacs from time to time, it's able to suck
all your memory.

To diagnose the problem, I used xrestop, a tool that "provides 'top' like
statistics of each connected X11 client's server side resource usage"
(http://www.freedesktop.org/Software/xrestop). Memory used by emacs goes
into the column "Pxm mem".

Am I the only one seeing this? Any idea?

Regarding the other thing (which is probably more a gnus thing), how come
some pictures are displayed internally and some others are not?

I could not find any error, but the value of image-cache-eviction-delay is by 
default 1800 (30 minutes).  You can try to lower it to a minute or so and see 
if it helps.  Also note that Emacs only clears images after every 50:th 
redisplay.  A redisplay is done very often (C-x C-f C-g triggers one, so does 
displaying a tool tip) so that should not be a problem.
