This is probing about a bit blindly, but the only thing I can see about this system that is in some way unique (and this is happening on multiple machines, so it's unlikely to be hardware) is that there are a relatively large number of relations (like, 440,000+) distributed over many schemas.  Is there anything that pins a buffer that is O(N) to the number of relations?
