Tomcat automatically shutdown after starting up.

Greetings.

I just downloaded and installed the Bonita community edition on a Windows Server 2012. After setting a MySQL database, i used the start-bonita.bat to start the Tomcat server.

In the beginning, the Bonita wars were being deployed normally. Later, after the server started up, it shows that a valid shutdown command was received, then closed automatically. The Tomcat console shows:

org.apache.catalina.startup.Catalina Server startuo in 72740 ms.
org.apache.catalina.core.StandardServer A valid shutdown command was received via the shutdown port. Stopping the Server instance.
org.apache.coyote.http11.Http11NioProtocol Pausing ProtocolHandler

after few more messages, the Tomcat server closed automatically.

How can i resolve this problem? Where did the shutdown command come from?
