我正在尝试通过visual studio 10中的“发布”设置创建一个新的Web角色实例。但是在发布过程中它似乎陷入困境：
13:30:32 - Warning: There are package validation warnings.
13:30:32 - Preparing deployment for PHPService - 02/04/2013 13:30:11 with Subscription ID 'xxxxxxxxxx' using Service Management URL 'https://management.core.windows.net/'...

13:34:39 - Instance 0 of role PHPWebRole is in an unknown state
13:35:14 - Instance 0 of role PHPWebRole is busy
它在忙碌时陷入困境，因此我无法使用我的网络角色。
为什么会发生这种情况，我该如何解决？
感谢。
