I've noticed it growing fairly large too. I've tried linking it with -lgnumalloc (Linux uses GNU malloc by default), and that seems to help (you can do this using the XFree86 LinkKit). We (XFree86) are doing some work on the malloc issue, both regarding memory leaks, and regarding methods to reduce fragmentation, and allow the system to regain freed memory. David
