Re: Why is this system swapping?

Using Resin's connection pooling. We are looking into pgpool alongside
slony to separate some reporting functionality.

Are you (Anjan) using real or fake connection pooling - ie pgpool

at pgpool. it does connection pooling correctly (A set of X connections
shared among the entire box rather than 1 per web server)
