Bonita is running 2 instances of Tomcat

Hi,

I have a persisting problem with Bonita BPM 7.3.2. It seems that Bonita keeps on running 2 instances of Tomcat and I always got an error saying that another Tomcat instance is running, while it was actually initiated by itself. I have not changed any of the config or properties files. I can't seem to find the problem and every time this issue appears, the only thing I can do to return it back to normal is to uninstall and reinstall it. It is now very time wasting for me to do that every single day. The problem usually occurs after I shut down or restart my laptop. EDIT: The problem occurs after restarting Bonita. Here are the logs:
