Thanks. Should "not working" cause the box to hang, or just cause the build to fail at some point with an error? I'm running a bog-stock snapshot install; I didn't try to get cute or clever anywhere, no customization, no non-stock sysctl settings, no mk.conf. I just installed the snap, checked out a tree, and built per the FAQ. I only went "off the reservation" by running 'make -j8 build' instead of 'make build'. I have just enabled ddb.console=1 and am going to try a series of builds with progressively higher -j flags. A -j4 build just succeeded. I'll report back to the list with full details if/when I can reproduce the hang. Thanks again... -- Joe Gidi j...@entropicblur.com "You cannot buy skill." -- Ross Seyfried
