mmm session is terminated since a blank receiving buffer cannot be required. connection name=aa....aa logical terminal name=bb....bb receiving buffer group number=n

mmm: MCF identifier

aa....aa: Connection name

bb....bb: Logical terminal name

n: Receive buffer group number

S: Ends the session.

O: Log on again from the terminal to start the session. If the same message does not appear again, the error was likely caused by a temporary receive buffer shortage, and you may continue operation. If this error occurs frequently, release the relevant connection or stop OpenTP1, and then contact the OpenTP1 administrator.

Countermeasure: There are not enough receive buffers. Increase the number of buffers in the relevant group in the MCF configuration definition.
