tomcat stops with CWPpro running CSF firewall

we have centos 7 with CWPpro and tomcat 8 on our VPS server

tomcat dies everytime, I refresh the status through CWPpro "Apache Settings" -> "Tomcat Manager"

Not sure what the heck is going on with CSF firewall. If we disable CSF and do the same steps, tomcat 8 runs fine without any issues
