CQMC0921E FAILED TO CREATE SOCKET ON PORT port_number
Explanation
The CAE Agent was unable to bind a listener socket to listen for connections from the CAE Server.
User response
Check that the port number is not already in use. Check that there are no restrictions (such as port list restrictions) that prevent the CAE Agent from listening on the port. This message should be followed with a tcperror message that should provide more details.
