mmm: MCF identifier

aa...aa: Connection name

bb...bb: Local port number

cc...cc: Function name (function name of TCP/IP socket (maintenance information))

dd...dd: Detail error code

-16718: The MCF communication configuration definition has multiple connections with the same configuration.

-16756: The number of file descriptors that can be used is insufficient.

Other than the above: Error number for TCP/IP failure

Check the value of errno returned by the OS.

S: If error detail code is -16718 or -16756:

Terminates the communication process.

For other error detail codes:

Retries connection establishment preparations according to the MCF communication configuration definition. If it does not retry connection establishment preparations, the relevant connection establishment preparations are suspended.

O: Contact the OpenTP1 administrator.

Countermeasure: Check the MCF communication configuration definition. If the local port number is the same as that used by another process, change the local port number in the MCF communication configuration definition to another value, or stop the other process. If the number of file descriptors that can be used is insufficient, in the system service common information definition, correct the maximum number of files that can be accessed in the MCF communication process.

If you are retrying connection establishment preparations while online for a connection whose establishment preparations were suspended, execute the operation command mcftonln.
