Hello
I have a server running tomcat on several ports and connections. All other
connections work as expected on this server and it has been working like this
for a number of years.
The error I get is

In the server.xml file I have
<!-- Define an AJP 1.3 Connector on port 8081 -->
<Connector port="8081" protocol="AJP/1.3" redirectPort="8491"
address="localhost"
secretRequired="false" />
do you have any suggestions as to the issue?
Something other than Tomcat is listening on port 8081 using ipv6.
Use "netstat -tnalp" to identify it.
If you want to limit AJP to ipv4, use address "127.0.0.1" rather than
"localhost". That might work depending on your OS.
