X Server Memory
I’ve noticed for quite sometime that as my computer is running over several days that the “xorg” process begins using more and more memory until eventually the performance of my machine suffers and I need to restart X. Is it the X-Server process that is “leaking” memory or is it something else leaking into the X process? Restarting X is not a terrible hassle but it doesn’t seem like normal behavior. Any thoughts?

I’ve seen that too. Firefox can be a major culprit, because it makes X map memory for all the images you view. Restarting it often helps.
Long running firefoxes are notorious for this.
me too. I object to having to restart all the time.
