Description

When an http enabled listener is deleted through the console, or via qdmanage ($management), it is being removed from the list of listeners (qdmanage query) but the router still listens to the related TCP port.

In the example below I had a router with an http listener on port 5674 and a non-http listener at 5672.

Here are the steps to demonstrate it:

• Start the router and query listeners

 

$ qdmanage query --type listener | egrep 'name'
"name": "listener/0.0.0.0:5672", 
 "name": "listener/0.0.0.0:5674", 

 

• Verify TCP ports being listened

 

$ netstat -anp | egrep tcp.*LISTEN.*qdrouterd
tcp 0 0 0.0.0.0:5672 0.0.0.0:* LISTEN 2887/qdrouterd 
tcp 0 0 0.0.0.0:5674 0.0.0.0:* LISTEN 2887/qdrouterd 

 

• Delete HTTP listener on port 5674

 

$ qdmanage delete --type listener --name 'listener/0.0.0.0:5674' 

 

• Query listeners

 

$ qdmanage query --type listener | egrep 'name'
 "name": "listener/0.0.0.0:5672", 

 

• Verify TCP ports being listened

 

$ netstat -anp | egrep tcp.*LISTEN.*qdrouterd
tcp 0 0 0.0.0.0:5672 0.0.0.0:* LISTEN 2887/qdrouterd 
tcp 0 0 0.0.0.0:5674 0.0.0.0:* LISTEN 2887/qdrouterd 

 

Note: This is only happening with http enabled listeners. Regular listeners are being shutdown properly.
