We have been running well for over a year using Postgres on a Linux
box and 2 Linux/AOLServer boxes. We used Redhat 7.0 for this
project.
The only issue I know of is something we haven't worried about or
looked into. The servers need to be able to talk to each other to
issue the util_memoize_flush command to each other. Since our site
isn't stressing our hardware we haven't used memoize much and when
we do the data is largely static.
