send error occurred at communication layer. pid=aaaaaa, port=bbbbbb(sport=cccccc), remote node addr=dd...dd, remote port=eeeeee(dport=ffffff), maintenance info=gg....gg(hhhh),ii....ii(jjjj)

aaaaaa: Process ID of the process with the error

bbbbbb: Receiving port number (listen port number) of the process with the error

cccccc: Sending port number (real port number^#) of the process with the error

A value of 0 is displayed in the following cases:

• Communication is performed on the local node (UNIX domain communication).
• The sending port number (real port number^#) cannot be obtained.

dd....dd: IP address, in dot (.) format, for the destination process (up to 15 characters)

eeeeee: Receiving port number (listen port number) of the destination process

ffffff: Receiving port number (real port number^#) of the destination process

A value of 0 is displayed in the following cases:

• Communication is performed on the local node (UNIX domain communication).
• The receiving port number (real port number^#) cannot be obtained.

gg....gg: Maintenance information (character string of up to 31 bytes)

hhhh: Maintenance information

ii....ii: System call name with the error (character string of up to 31 bytes)

If the name cannot be displayed, "******" is displayed.

jjjj: errno value of the system call with the error

A value of 0 is displayed if there is no system call error.

A real port number refers to the port number that is actually used for sending and receiving data. For send processing, OpenTP1 establishes a connection for the listen port number of the destination process. OpenTP1 does not disconnect the established connection and re-uses it for the same inter-process communication. As a result, the port number actually used for connection might be different from the listen port number of the destination process depending on whether there is an established connection and the direction of the established connection.

As with the case of sending, the receiving port number might also be different from the listen port number of the local process depending on whether there is an established connection.

S: Either returns to the source of the RPC service call or continues the processing.

O: If the output of this message causes, UAP processing to fail examine the cause using the system call name and error value.

If the cause is unidentifiable, store the file under $DCDIR/spool of the host where this message appeared and of the host that is shown in this message and the file under $DCDIR/spool/save, and contact the OpenTP1 administrator.

Countermeasure: Contact the maintenance personnel.
