Took a while to find just how to reduce the number of memories from 2 to 
1.  It turns out to be possible, but against all intuition the single 
memory had to be installed in the second slot, which was named A1.

Got the machine wo work for awhile with only one G memory, then it 
crashed in the usual way.  Tried it with the other memory in that slot, 
and it worked for longer, but still got around to crashing today.

It crashes quickly when running Pan, when using mozilla firefox with 
complex web pages, and slowly when using xjig.  Other things probably 
crash it too.

It took a while to get to the tests involving Pan and the complex 
web0sites, because just to complicate things the DSL line I use for 
network died and the phone company had to get around to fixing it.
But they crashed quite quickly when I finally got around to it.

I have an idea that it is network activity (the mouse in X also talks on 
the net internally, I believe) during graphics activity that does it in.
No definitive evidence for that, but I do seem to be doing both when it 
goes down.

Once again, when it crashes, I can sometimes still manage to use a ssh 
connection to get in from elsewhere.  What information should I collect, 
and how should I analyse it?

2x1G.  But now I'm running 1x1G.  Kingston memory.

memtest86+ never finds a thing wrong.

Could be, of course that it's other hardware.
