Hello,
This is strange... I agree that the log states that the Message Server opened the HTTP port 8100.
But as you can see, it is an ABAP instance that is responding requests made to that port.
Did you configure the ICM to also use the port 8100?
Either that, or the hostname sapprdcluster.awqaf.gov.kw is not pointing to the Message Server host, but to an ABAP host.
Confirm that the hostname is pointing to the correct server.
Then logon to the ABAP instance and access the transaction SMICM, menu goto -> services.
If you have an HTTP port 8100 there as well, you need to change it (or change the HTTP port of the Message Server...).
Regards,
Isaías
