Comment 17 for bug 98783

Another data point. I'm having the same overall issue using the radeonhd driver on my laptop, so there may or may not really be an issue with leaks in the nvidia driver. It sure seems to be related to firefox and flash content as the memory usage of the xorg process ramps up when I run firefox (1.5.x thru 3.0.5) and ramps up exponentially faster for pages that have flash content. Killing/quiting firefox frees up a lot of memory, but not from Xorg's overall total. It has behaved like this (for me) for the past couple of years. Only reason it's not a big deal for me is I'm constantly having suspend/resume issues since the 7.10 release, so uptime never exceeds a couple of weeks anymore. :(
