Why can't I start a debug session on Eclipse using Xdebug?

I've been debugging in Eclipse with Xdebug without any problems, but for some reason since this morning, when I try to start a debug session, I get an error like this from Eclipse:

"The file 'http://localhost/index.php?XDEBUG_SESSION_STOP_NO_EXEC=ECLIPSE_DBGKEY=13288911493954' could not be found.

In my phpinfo file, I can see that Xdebug is working.

I'm using Elipse 3.7.1, Xdebug 2.1.3.

This is the Xdebug config in my php.ini file: zend_extension = "c:/wamp/bin/php/php5.3.8/zend_ext/php_xdebug-2.1.3-5.3-vc9-x86_64.dll"

[XDebug] 
xdebug.remote_enable=On
xdebug.remote_host="localhost"
xdebug.remote_port=9000
xdebug.remote_handler=dbgp

Any help will be greatly appreciated.

Solution

The message you receive is because Eclipse is trying to stop a debugging session. It's a wrong URL as well, as it should really say "http://localhost/index.php?XDEBUG_SESSION_STOP_NO_EXEC=1". Why it wants to stop, I can't tell you, but the ?XDEBUG_SESSION_STOP_NO_EXEC=1 gets captured by Xdebug and makes the request not proceed. To find out, you can perhaps use the xdebug.remote_log setting (http://xdebug.org/docs/all_settings#remote_log) to create a log file on what Eclipse is trying to get Xdebug to do.
