Web Application Warning Messages

Warning Messages List

200 - Start Web Application denied, the server is currently shutting down.

Occurs if a new Web Application is trying to start when the service is shutting down. All new Web Applications are denied when the service is shutting down.

201 - A child process does not respond, unconditionally terminating the process ProcessName.

Occurs when the DataFlex process is hung. Usually indicates that the DataFlex program doesn't respond. The service will force a process terminate and any unsaved data will be lost.

If possible, set up "Allow service to interact with desktop," or some other means of debugging the DataFlex process. This could indicate errors such as infinite loops in the DataFlex program.

202 - ApplicationName Session: SessionId From: IPAddressOfRequest

A timeout occurred during transaction call. Session aborted and all pending I/O cancelled.

Occurs when a transaction timeout occurs (default 2 minutes). Usually indicates that the DataFlex program doesn't respond. Can also occur if processing in DataFlex takes longer than 2 minutes without communication with the Web Application Server service, e.g., very heavy processing within a method without any messages sent back to the service.

If possible, set up "Allow service to interact with desktop," or some other means of debugging the DataFlex process. This could indicate errors such as infinite loops in the DataFlex program.

The transaction timeout can be changed in the Administrator.

203 - Application: ApplicationName Session: SessionId From: IPAddressOfRequest

A timeout occurred during message transfer. Session aborted and all pending I/O cancelled.

Occurs when a message being sent does not receive the destination within the default 20 seconds. Usually indicates that the DataFlex program doesn't respond, i.e., the DataFlex process is hung. Note that this does not mean that the message must be processed within 20 seconds; it just needs to reach the destination queue within 20 seconds.

The message timeout can be changed in the Administrator.

If possible, set up "Allow service to interact with desktop," or some other means of debugging the DataFlex process. This could indicate errors such as infinite loops in the DataFlex program.

This could also occur under very high server load.

206 - Bad service request.

Occurs when the service receives an unknown request. This error is internal and should not normally occur.

208 - Application: ApplicationName Session: SessionId From: IPAddressOfRequest

Session denied, %4.

Occurs when a new session attempts to be established while the service is currently shutting down. Somewhat misleadingly, this error is also reserved for future use where the session is refused for some other reason, such as a bad login, etc.

214 - Application: ApplicationName Session: SessionId From: IPAddressOfRequest

A communication error occurred. %4 Session aborted and all pending I/O cancelled.

215 - Application: ApplicationName Session: SessionId From: IPAddressOfRequest

A fatal session error occurred in the child process. %4 Session aborted and all pending I/O cancelled.

216 - Connection with remote node NodeName failed: %2. Please verify the IP address, port number, and the network connection.

217 - Incoming connection from NodeName rejected. NodeName is not in the list of valid master nodes allowed to connect to this machine. See the load balancing tab in the options dialog in the DataFlex Web Application Server Administrator.
