mmm connection name=aa....aa logical terminal name=bb....bb kind=cc....cc receive buffer length=dd....dd received message length=ee....ee unreceived message length=ff....ff

This message reports additional information when a reception buffer overflow is detected. It is output together with the KFCA14806-W and KFCA14816-E messages.

mmm: MCF identifier

aa....aa: Connection name (connection ID of MCF communication configuration definition (mcftalccn -c))

bb....bb: Logical terminal name (logical terminal name of MCF communication configuration definition (mcftalcle -l))

cc....cc: Segment assembly type

MASM: Assembly facility for received messages

UOC (STD): UOC for determining input segment, provided as standard with TP1/NET/TCP/IP

UOC (USR): UOC for determining input segment, specific to user

dd....dd: Length of buffer that stores received messages

ee....ee: Received message length

ff....ff: Unreceived message length

For MASM or UOC (STD) segment assembly types

The difference between the message length specified in the message length area (first 4 bytes of received message) and the length of already received messages

For UOC (USR) segment assembly type

Size of remaining relevant messages (rest_data_size of dctcp_sguoc_prot)

Countermeasure: Determine whether the total length of received messages (the sum of already received messages and unreceived messages) is appropriate.

If total length of received messages is appropriate:

Carefully review the length of the buffer (in mcftbuf -g length) specified in the buffer group definition.

If total length of received messages is not appropriate:

If the segment assembly type is MASM or UOC (STD), carefully review the remote system. If the segment assembly type is UOC (USR), carefully review the remote system and the user-specific UOC for determining input segment.
