He did say what his mail average is: "This is a small-scale family server receiving only about 250 emails a day." You may want to read the entire message next time. Thanks, JamesDR

You don't say what your normal mail rate is, nor what rules you are running.
2.64 didn't have some of the memory problems that were really bad on the initial 3.0 release, and are now largely corrected. Generally all that would cause the sort of thing you are seeing would be either running too many spamd children for the available memory, or using some of the really big addon rule sets like BigEvil.
How many spamd children do you have running? You should probably limit to 3-5 at most with 512M, at a guess. Are you using BigEvil? If so, get rid of it and use the surbl patch instead.
You are clearly getting into swap, and this implies that you have overflowed memory.
