The problem occurs when i try to access the administrative interface:

1. On the server I open IE and type the URL: http://localhost:8095/crowd. I get the login screen.
2. I type the admin username and password.
3. When clicking login the computer freezes, and sometimes I get errors from Java.

In the task manager I can see that one of the Tomcat instances uses nearly 100% of the CPU resources.

This problem occured when Crowd was installed as a Windows service. Running it from the .bat file in a console window worked fine.
