We have an instance running in single node running on Windows. I saw that it opens a lot of connections to itself. Like:
TCP 127.0.0.1:9200 127.0.0.1:52540 ESTABLISHED 21936
TCP 127.0.0.1:9200 127.0.0.1:52669 ESTABLISHED 21936
TCP 127.0.0.1:52541 127.0.0.1:52542 ESTABLISHED 21936
It seems these ports (52540, 52669, 52541, 52542) are random.
However I have another application uses some port from 50000-60000. This application may stop working if the port is already used.
Is there any setting to disable this? Or can I modify the setting of this port range?
I tried http.port, transport.port. But they did not work.
