java.net.BindException: Address already in use on tomcat - tomcat8

Question

I keep getting this bind exception in the logs while have tomcat process running.
It doesn't prohibit my process from start but still this is a problem.

What have I tried already:
lsof | grep -i process/port/ip
netstat -tlnp
I tried to find if any other application is using the port or not. But no other application is using it.
It is free linux centos.

Answer 1

It is strange.
ok.
Even the SEVERE exception is there in the logs of catalina but I can get to the server and get landing page.
Still I have to figure out why did it keep writing that Exception.
