Thanks for the tips, all who responded (including a few who responded via email-only --- Kris, thanks for not just calling me an idiot outright. <-; BTW, thanks for your BSDCan presentation ... really motivated me to try to get the 5.x boxes I have in production upgraded! I'll say no more...). This was a false alarm. The box in question is being monitored fairly closely with some home-brew rrdtool graphs, and there was a definite corelation between the load and the paging graphs. The problem was confusion regarding the *scale* of the graph. The rrdtool graphs add an "m" to indicate the numbers are in the "millis", when the frequency scale is less than 1 (per second), rather than using decimal places. This was not noticed. So the massive swapping was actually miniscule. Sorry about that.
