Answer 1

I had the same problem with an Ubuntu Linux server running subversion when accessed via Eclipse.

It has shown that the problem had to do with a warning when Apache (re)started:

[Mon Jun 30 22:27:10 2014] [warn] NameVirtualHost *:80 has no VirtualHosts

... waiting [Mon Jun 30 22:27:11 2014] [warn] NameVirtualHost *:80 has no VirtualHosts

This has been due to a new entry in ports.conf, where another NameVirtualHost directive was entered alongside the directive in sites-enabled/000-default.

After removing the directive in ports.conf, the problem had vanished (after restarting Apache, naturally)
