Comment 8 for bug 1586054

I got this issue during an upgrade but it was actually caused by a ghost of tomcat still running (so the start was failing because the ports were already in use). No idea how the service got lost.

so if you have this error:
* make sure you called "/etc/init.d/tomcat8 stop"
* check with "ps aux | grep java" if you still have a running Tomcat
* if that's the case kill it
