Issue:
When starting up the Tomcat service on your PPM/Japsersoft Server the console displays error java.net.BindException: Address already in use: bind. The error also displays in Catalina.log.
Environment:
CA PPM/Japsersoft
Resolution:
This is likely caused by another Tomcat instance process is already using this port. The error implies that there is already a service running on port 8009. If the service is running on 8009 is needed you could change the connector configuration in server.xml to something like below:
<Connector port="8089" protocol="AJP/1.3" redirectPort="8443" />
