I suspect that this is caused by one of two things:

1. You haven't specified which minor version of PostgreSQL 8.1 you are
running, but if it's not the latest one (8.1.19) you should upgrade.
There may be data corruption bugs that have been fixed in newer
versions.  I would suggest a dump and reload cycle to make sure you've
got a clean install, if that's practical.

- or -

2. Your hardware is busted.
