	TCP target buffer overload by Francis * :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hi, When sending a large string (68000 characters) to a TCP target I get this exception. I am using NLOG (.NET 2.0) v. 0.95 (I think, it shows 1.0.0 but that can't right). Error Target exception: System.Net.Sockets.SocketException: A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than the datagram itself at System.Net.Sockets.Socket.SendTo(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags, EndPoint remoteEP) at System.Net.Sockets.Socket.SendTo(Byte[] buffer, EndPoint remoteEP) at NLog.Internal.NetworkSenders.UdpNetworkSender.DoSend(String text) at NLog.Internal.NetworkSenders.NetworkSender.Send(String text) at NLog.Targets.NetworkTarget.NetworkSend(String address, String text) at NLog.Targets.NLogViewerTarget.Write(LogEventInfo logEvent) at NLog.LoggerImpl.Write(Type loggerType, TargetWithFilterChain targets, LogEventInfo logEvent) Thanks, Francis ------------------------------------------------------------------------- Using Tomcat but need to do more?

What should we do about it? There are 3 options: * quietly discard the message * throw an error * split the message into smaller pieces. I propose the following attributes be added to the Network target: maxChunkSize (default = 65000) bufferOverflowAction=Discard\|Error\|Split What do you think? If we are quick, I believe I can add them before 1.0 ships. Jarek ------------------------------------------------------------------------- Using Tomcat but need to do more?

	Re: TCP target buffer overload by Francis * :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Jarek, Ah right the protocol limitation, I didn't think of that. What is the use of discarding a message or throwing an error? I would simply have the target automatically split if size > 65000. Of course what you propose is a nice feature but personally I don't see a use for it.

Of course what you propose is a nice feature but personally I don't see a use for it. Assume you have a receiver that accepts XML-formatted messages and your message is 65010 bytes long and is <message>............... ... </message> If you split the message after 65000th byte, then neither part will be a well-formed XML, because the first will be "<message>............... ... " and the second one will be: "</message>". Dropping a such a packet might be a good idea. Throwing an error might give you a hint that some packets are actually dropped (you can use FallbackTarget to log to a file in case of an error).
