Rails:freeze:edge hanging...?

Does this ever happen to anyone else ? It happens to me all the time.
It will get part way through downloading all the new stuff and then
just sit there. If I kill the svn process, another one starts where it
left off, but then my rails app is all goofed up and I can’t do
freeze:edge again because somefile is missing now. Is this some kind of
NAT problem or something? It doesn’t work more often than it works, but
it does sometimes work.
