nameserv abnormal error occurred

Hello, I'm contacting you because I have an inquiry
One day, when I started the visibroker, the status of NAMESERV appeared as ABNORMAL.

This is log.

So, I conducted a test with visibroker using bank_agent.

This is test log.

----------------------------------------------------------
As you can see, even the makefile_java did not work.
I would like to know the cause of this. Do you have any guesses?
I think It is suspected that the issue is due to a port number conflict on the equipment where Visibroker is installed.
Or, if there is something more we need to investigate to solve this problem,
please let me know and I will try it. Thank you.

Visibroker's version is 8.5 CORE PROD, Developement.
