What is causing this error?

Environment

Release : 1.1

Resolution

In most cases, the EDC5111I error is an indication that the port number is reserved for another task. Issue a TSO command netstat,portlist or OMVS command onestat -o to display what port numbers are reserved and for what job names. Port numbers are reserved in the TCPIP PROFILE and it could be that the TAMSTC default 8080 port is reserved for another task.
