DCSV9410W: Failed to allocate memory: {0} bytes. Exception is {1}.
Explanation The transport layer (RMM) failed to allocate enough memory to receive an incoming message. Action Consider increasing the JVM memory heap size or decreasing the workload of other members.
DCSV9411E: Encoding {0} not supported on this host. Exception is {1}.
Explanation The transport layer (RMM) failed to encode or decode a string because the local operating system does not support the specified encoding. Action Configure the local operating system to support the specified encoding.
DCSV9412W: Failed to resolve internet address {0}. Exception is {1}.
Explanation The transport layer (RMM) failed to resolve an internet address. This problem might indicate that there is a DNS problem. Action Check the DNS environment.
DCSV9413W: Failed to set buffer size on the socket to {0}. Internal details are {1}. Exception is {2}.
Explanation The transport layer (RMM) failed to set the buffer size on the socket. This probably indicates a configured limitation in the operating system. This limitation may lead to poor transport performance. Action Check the network configuration for the operating system.
DCSV9414E: Failed to bind a socket to address {0}. Exception is {1}.
Explanation The transport layer (RMM) failed to bind a socket to the specified address. This problem probably indicates that the specified port is already in use. Action Check configuration of the server socket port.
DCSV9415W: Received packet larger than configured buffer length {0} from RMM address {1}. Exception is {2}.
Explanation Another machine sent a packet that was longer than the configured buffer length for incoming packets. This problem might indicate that another application is using RMM with a larger configured packet size or that a malicious sender attempted to send large packets to the local machine. Action Check the identity and configuration of the specified sending machine.
DCSV9416E: An internal error occurred. Exception is {0}.
Explanation An unexpected error occurred. See the exception stack trace for more detail. Action See the problem determination information on the WAS Support Web page: //publib.boulder.ibm.com/infocenter/wasinfo/v8r0/index.jsp?topic=/ ://www.ibm.com/software/webservers/appserv/was/support for additional information.
DCSV9417W: Failed to send a UDP packet to address:port {0}. The exception is {1}.
Explanation The transport layer (RMM) failed to send a UDP packet because of a connectivity problem. Action Check the network connectivity.
DCSV9419W: Failed to set socket parameter {0} to {1}. Exception is {2}.
Explanation The transport layer (RMM) failed to set a socket parameter. Action Check the network configuration for the operating system.
DCSV9420W: Received an incoming connection with a tag that exceeds the configured maximum length. Source address is {0}. Length of the received tag is {1}. Configured maximum tag length is {2}. Exception is {3}.
Explanation The transport layer (RMM) received an incoming connection with a tag (queue name) that exceeds the configured maximum length. This problem probably indicates either a maximum topic size configuration problem or that a malicious tampering with wire format has occurred. Action Check the identity and the configured maximum token size of the specified sending machine.
DCSV9421W: General networking problem occurred on socket address {0}. Exception is {1}.
Explanation A general networking problem occurred on the indicated socket address. Action Check the network configuration.
