We've been running 7.0 on a linux server since RC3 on a database with
over 40 million tuples without this problem (all 40 million tuples are
indexed on 3 fields).  So I'm not sure I see how it can be concluded
that this is a linux problem.

I just restarted a different server 50 consecutive times and I cannot
reproduce this error either.

(Both these are Redhat 6.2.  We also have postgreSQL 7.0 running on a
few Redhat 6.1 servers).
