Well, interesting! I don't know if this is related, but I've already feared 
I'm slowly going insane, because one of my 4-STABLE boxes has also started to 
crash occasionally lately. In fact, it was running rock solid before and now 
I get something that I seem to be able to reproduce whenever I try. It's a 
panic with trap 9 and not trap 12 I get here, but I thought I'd mention it 

Basically, my strange story goes like this: When I have X and KDE (3.2) 
running on my machine as a normal user and then switch to another virtual 
console, log in there as root and run a "make NOCLEANDEPENDS=yes clean" 
in /usr/ports, in 100% of all cases. Really - it crashed every time I tried 
since I first noticed about two weeks ago.

What I find really strange: On the very same box, I've had KDE run non-stop 
for 7 days without a break and without a crash. I've ran a "make buildworld" 
while X11/KDE was running - no problem! And I've cleaned my ports tree while 
KDE was *not* running - also successful. Only when KDE is running and I'm 
cleaning my ports tree, strange things seem to start to occur.

I'll probably get myself a memory dump and a backtrace and post more 
information here if there's interest, but for now here are some details I can 
already give at this time:

I'll keep having an eye on this, but if someone already has a clue what's 
going on here. ;-)
