Tomcat sitting on port 8080

Self-hosted Confluence 7.2.0.

Confluence is running HTTPS on port 443.

Confluence's tomcat is sitting on port 8080 (and others), blocking others from serving up on port 8080.

Is there a config to disable this behavior?  Is the only option to launch Confluence after everything else is running, just to keep Confluence from sitting on ports that it isn't using?  This did not happen in the prior 7.1.x build.

Hi @David Crowder ,

By default Confluence sits on port 8090. This can be changed by editing server.xml and specifying a port number.

<Connector port="8080"

No, this is not the active HTTP port.  This is something different.  Confluence's tomcat process is opening multiple ports in the background, for what purpose I do not know, and just leaving them open.  These ports are not the port that users connect to for HTTP(s) sessions, but are other often-used ports, such as 8000 and 8080.  Confluence's opening them and sitting on them blocks other applications from their use.  It did not previously behave in this manner.


You can observe this with any common tool to monitor an application's listening ports.  Confluence 7.2.0 will be sitting on ports 8000 & 8080 (and many others) in addition to whatever HTTP port you have it configured to use.


So, I'm trying to find a way to stop Confluence from this behavior.
