SUMMARY: Problem on ES40

From: Peter.Stern@weizmann.ac.il

I wish to thank the many people who tried to help:

Thierry Faidherbe
Rudolf Gabler
Joe Fletcher
Benjamin C. Ingwer
Guy Noce
Paul Maglinger
John Lanier
David Gutierrez
Richard Loken
Martin Roende
Fernando Carnero

Several people suggested reseating the memory modules.

John Lanier suggested using WEBES (Compaq Analyze on my machine) to
translate the binary error log and sent some tips on how to do that.
This identified the relevant DIMM.
