Possible Memory Leak leading to Cedega Crashes?
 

I've been trying to figure out a problem I've been having in Ubuntu for a while now. The problem exists with Transgaming Cedega and City of Heroes mostly, although it may affect other games as well.

Basically what's happening is that if I play immediately after restarting my computer everything is fine and I can play for over an hour without having any problems, but if I leave my system running overnight the memory monitor I'm using (the default Gnome one that's in the panel) shows that over 80% of my memory is being used and over 50% of which is Cache. If I try to play then, I can only get about 30 minutes of play in before Cedega crashes the game and I get this error: http://www.viruscore.com/pictures/Screenshot-7.png

I'm wondering if there's a possible memory leak somewhere in Ubuntu that may be causing this. How would I find what is causing the excess memory usage?

Any help would be greatly appreciated.

Thanks

I would try saving, or quitting for a second...and then killing all of your wine processes. Restart the game, and see what happens.
