I'm don't think in this case that its a mem leak, I still show almost 
all of my memory available. Whats weird, is that this is only occurring 
when KDE itself tries to launch a process / program.

For example, I have a firefox icon in kmenu, or desktop. At random 
times, I'll click the icon, and it'll just sit there, without launching 
at all. However, if I have konsole up, I can run firefox manually, and 
it starts / exits just fine. The weird thing is that it'll go ahead and 
start firefox up after a few minutes in some cases. (No errors or 
anything, it just starts minutes later) Its almost as if KDE is waiting 
for a call, or some dbus request to finish before starting the application.

Few more details about our setup:

KDE 4.1 (latest from ports)
FreeBSD 7-Stable
ULE Scheduler

Aside from that, nothing too special. KDE 3.5.x never had this problem 
on 7-Stable.
