I've also noticed this...  Sunday and yesterday, I deleted ALL installed -ports and 
-packages thinking that the meinproc issue with 
kde-2.2 was being caused by conflicts in libraries and/or include files [it's not 
either] on this system which has had about three 
years since a good clean scrubbing...

While I was busy recompiling the basics, I noted that the disk activity would stop, 
and the console become non-responsive, yet there 
was no panic or other kernel message.  This was happening consistantly for about 12 
hours or so, and I had to back down from 5 or 6 
parallel -ports compiles to one and two in parallel.

I also have noted that when switching VTY [by hand, or when exiting X] the system 
would panic on mwrite and give message about the 
possibility of buffers being wierded out POSSIBLY [the message was a question].

I also noted on several instances that the "freezes" would occur when there is heavy 
disk and CPU activity combined with network 
access [this may or may not be a contributing factor, I don't know] such as fetching a 
distribution file.

I have also noticed extreme slowness when disk activity occurs.  top will show almost 
no CPU being used, but when there is something 
being copied or moved, everything becomes REALLY sluggish.  This has only been noticed 
in kernels of the last month or so.

I noticed a lot of changes last night, especially in the vm code, and I'll wait and 
see if this fixes anything I've noted...  Man 
them cvsup servers were slow this morning!
