Transport chain problems
Review the following topics if you encounter a transport chain problem.
TCP transport channel fails to bind to a specific host/port combination
If a TCP transport channel fails to bind to a specific port, one of the following situations might have occurred:- You are trying to bind the channel to a port that is already bound to another application, such as another instance of a WAS.
- You are trying to bind to a port that is in a transitional state waiting for closure. This socket must transition to closed before you restart the server. The port might be in TIME_WAIT, FIN_WAIT_2, or CLOSE_WAIT state. Issue the netstat -a command from a command prompt to display the state of the port to which you are trying to bind.
If change the amount of elapse time that must occur before TCP/IP can release a closed connection and reuse its resources, see Tuning operating systems.
Error message CHFW0030E indicates there is
"No such file or directory,"
![[HP-UX]](../../hpux.gif)
If you receive an Error message CHFW0030E that indicates there is no such file or directory, and you are running on an HP-UX operating system, make sure you have the most current patches for that operating system installed.
