Folks, Hate to follow myself up, but - on the one 9.1-STABLE machine where the disk i/o bogging down issue was a showstopper, I fixed it by reverting to 8.4-STABLE. Symptoms instantly went away, box became performant and responsive. regards, Ross -- Ross Alexander, (780) 675-6823 / (780) 689-0749, rwa at athabascau.ca "Always do right.
