Glad to hear that :-) Thanks for the report!

You were right. In the log of the outer firewall I found:

proto=53/udp src=80.136.74.216 dst=217.237.150.115 msg=Ceiling for
number of connections reached, dropping packet Src 1390 Dst 53 from SELF
n/w

It seems, the firewall was overwhelmed by DNS requests. The same
apparently often happens with bitTorrent and similar tools when using
this sort of hardware (a Linksys firewall). I should go back to a
self-maintained, Linux-box as firewall or setup a local, more
intelligent DNS.

Is there a chance to limit the amount of simultaneous DNS requests in
buildout? Or to get the names of failed eggs displayed when running
buildout without '-v'?

Right, again.

Now it's:

[buildout]
index = http://download.zope.org/ppix
eggs-directory = /home/uli/buildout-eggs
newest = false
download-cache = /home/uli/eggs/download-cache

and yes, with ppix it works much smoother (although still errors occur,
but *far* less than before). Thanks for the hint! Now I know where to
catch the problem :-) Sorry for the off-topic.

Good hint! Use it, guys!
