 Suddenly (without changing my Avalon installation) I get Corba connection
 errors, a simple example is this one:

 I already tried {{{sudo /etc/init.d/omniorb4-nameserver restart}}} and
 {{{sudo /etc/init.d omniorb4-nameserver force-reload}}}, but it did not
 help.

 The original problem was this:

 {{{
