Hi,
i have problems using ext-gen behind a proxy. During the generating process npm opens more than 150 connnections.
This is a know issue, and should be fixed in newer npm versions...

As an workaround I try to use this:
https://www.npmjs.com/package/tcpfwd-maxconc-pmb
... but on my windows machine it seems not to work correctly
Perhaps you at Sencha can something do for limiting the connections?
Bye, Dumbledore
