The process normally listening, the service stopped working. (manage-sieve, TCP port 4190)… After looking at netstat I see 300+ connections on this service in a “CLOSED” state… All of the connections are via IPv6. Sockstat shows all of these connections not related to a user, command, pid, etc…. If I restart the process, all of the connections are freed and things work as expected for a while. sockstat USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS ? ? ? ? tcp6 dead:beef:110:2::1:0:25 dead:beef:110:2::f:0:24162 ?
