}	You are definitely short on swap space!  My rule of thumb is to
}allocate at least twice the swap space as real memory and make sure memory
}is reasonable.  How much REAL memory do you have.  Add that plus your swap
}space and that's your virtual memory.  I don't think I'm configuring anything
}with less than 64Meg of swap anymore...  Kernel compiles do eat memory too...

You know this swap thing, I'm not too sure.  I posted a question a while back
as to whether this 2X rule of thumb should apply when you have a large
amount of real memory.  Well, besides getting flamed for asking a stupid
question, the impression I got was that it applies to a point.  Well, I still
don't know the answer, but I do know that when I had 16 meg of real memory
and a 32 meg swap, X was doing a lot of swapping.  I've since upgraded to
40 meg of real and left my swap at 32.  I see very little swapping now
with X and kernel compiles run fine.  So, with the possibility of the
flame jerk rearing his ass, I would pose the question again, but I won't.
Point is, I don't have a problem with 40 meg real and 32 swap.  Free looks
okay too, example with X running, three xterms, xeyes, xdaliclock, xbiff,
xload and netscape:

             total       used       free     shared    buffers     cached
Mem:         38976      28268      10708      17884       2568      14772
-/+ buffers:            10928      28048
Swap:        33260          0      33260

Still have plenty of real memory available, and after a few samples during a
kernel compile here's the worst:

             total       used       free     shared    buffers     cached
Mem:         38976      38500        476      21520        980      21812
-/+ buffers:            15708      23268
Swap:        33260         72      33188

Still, very little swap used and some real memory hanging around.  So, if
anyone has a better rule than the 2X rule, I'd like to hear it.
