The system is waiting for assigning the Connection object. Profile ID = aa....aa

The system is waiting for another connection to be released because the number of connections in use has reached the maximum and there are no free connections in the connection pool.

aa....aa: Profile ID of the configuration definition

S: Waits until a connection in use is released and then allocates it. The KFCA32404-I message is output when allocation of the connection is complete.

O: If this message frequently appears, the number of connection pools may be insufficient for the number of connections being used concurrently. Increase the number of connection pools and then retry. If this message appears when a sufficient number of connection pools has been specified, an application might not have released connections. Make sure that the connections were released (the TP1Connection or TcpipConnection Dispose method was executed) when the application terminated.
