Thanks Bert,

I was hoping that was the case. It sounds like I need to educate myself as
to how to migrate the old squeaksource.com to an image like the one we are
using for source.squeak.org.

Would you mind putting a copy of the image and changes files for source.squeak.org
on box3 so I can take a look at it (I don't have access to box2)? Thanks.

Meanwhile I'll keep an eye on the socket leak and restart the squeaksource.org
image as needed.  I'm guessing that this will be required about once per week
at the current rate of leakage.
