[xdebug-general] Can't start xdebug, refuses to connect

Hi, I managed to install xdebug and enable it through local php.ini files
when needed. It was working just fine for about a month, but today It
doesn't.

If I try to start a debug session with Zend Studio IDE, it gets stuck in
"57% launching: waiting for xdebug session"

phpinfo reports Xdebug v2.1.0

local php.ini
 Quote:
  zend_extension='/usr/lib/php5/20090626/xdebug.so'

[xdebug]
xdebug.remote_autostart=Off
xdebug.remote_enable=On
xdebug.remote_connect_back = On
xdebug.remote_port=9000
xdebug.remote_handler="dbgp"
xdebug.profiler_enable = Off
xdebug.profiler_enable_trigger = On
xdebug.profiler_output_name = cachegrind.out.%t.%p
xdebug.profiler_output_dir = '/media/data/www/clients/client1/web2/tmp/'
xdebug.remote_log='/media/data/www/clients/client1/web2/log/xdebug_didomenica.log'

Specs
Ubuntu server 12.04, upgraded today
PHP Version 5.3.10-1ubuntu3.4
Xdebug v2.1.0

Any help is really appreciated!

Thanks a lot!
