It's a database machine running MySQL and Postgres.  The
MySQL server runs about 4 queries/sec and PostGres only as

messages per minute and runs apache at about 10 requests
per minute.

Just tried with mem=900m and subsequently mem=850m so as no
himem pages were available with no effect.  Machine still
crashed.
