Tomcat 9.0.30 on Windows Server 2012 / Java 1.8 I've noticed on a freshly installed version of tomcat 9, upon startup there are several connections to and from localhost on different ports
For example on my tomcat server there are 4 connections to and from localhost (output from netstat) TCP 0.0.0.0:8080 0.0.0.0:0 LISTENING 3972 TCP 127.0.0.1:55618 127.0.0.1:55619 ESTABLISHED 3972 TCP 127.0.0.1:55619 127.0.0.1:55618 ESTABLISHED 3972 TCP 127.0.0.1:55620 127.0.0.1:55621 ESTABLISHED 3972 TCP 127.0.0.1:55621 127.0.0.1:55620 ESTABLISHED 3972 TCP [::]:8080 [::]:0 LISTENING 3972 These can grow to a large number (several thousand) on a busy system. What are these connections used for? What caused them? What thread are they attributed to?
