I have a problem with one of my 4D20s.  It will occasionally crash with
a memory error (PANIC: IRIX killed due to memory error at physical address
0xXXXXXX).  It will do this about 4 times over a couple of days, and then
it's fine for a month or more.  Then it does it again.

The problem is that the error is not always in the same place -- not even
in the same bank.  And when I run IDE diagnostics, it says there's 
nothing wrong with the machine at all.

Any suggestions will be most welcome.

I was having a similar problem with my Crimson last week ("PANIC: KERNEL FAULT"
and a "Bad address" which was different every time).  SGI was ready to send
me a new CPU board, but now I think the machine has been overheating because
my acoustic foam panels were packed too closely around it.  I had had no problems
with this configuration for the past four months.
