We have 1GB allocated to our smallest container which also runs a Java
application, albeit not Alfresco, and it worked fine on Lenny/amd64, with Sun
Java 6 underneath.

Anyway, yeah, that is the sort of tuning I was talking about. :)

Er, I don't actually know, but you might need to use a veth device rather
than a venet device for the Alfresco SMB share thing to work.  If that is the
document management thingy which does SMB/CIFS sharing, that is. :)
