An established connection was aborted by the software in your host machine

hi,

We found following errors in the log. An established connection was aborted by the software in your host machine. Does that really mean the connection was terminated by host host machine?

Also, it took six seconds to recover. is there any chance we could make it shorter by config?

Many thanks,

Brian

Hi @blam

The message does indeed mean that your application was disconnected by the server.

This could be because there was a problem with the server or your network. Please check with your market data to confirm if this was the case- they should be able to examine their ADS logs to check.

However, quite often this disconnect can also happen because your application is not processing the data from the server quickly enough.

The server can only buffer so much data before it has to disconnect the application once the buffer is full.

A common cause of this is when your application is spending too much time processing the data in the OnRefresh / OnUpdate callback handlers. These callbacks are executed on the API thread and the more time the API thread spends in the callback handlers, the less time it will have to read data from the server.

Ways of alleviating this situation include:

minimising the processing done in the callback handlers with the API thread, by offloading some processing to a seperate application level thread
splitting your instruments across more than one OmmConsumer instance i.e. horizontal scaling as demonstrated in example410

Hi @blam,

There are reconnect configuration parameters within the EMA config guides (reconnectMinDelay/reconnectMaxDelay) which you can configure.

Jirapongse

From
the error text, I assume that the operating system is Windows and the error
code could be WSAECONNABORTED (10053). Refer to the Windows Socket Error
Codes page (https://docs.microsoft.com/en-us/windows/desktop/winsock/windows-sockets-error-codes-2),
WSAECONNABORTED is “Software caused connection abort.”.

Therefore,
it could be a network issue. To verify the problem, you can use a network
protocol analyzer tool, such as Wireshark (https://www.wireshark.org/)
to monitor data transmission time-out on the network and verify which side that
cuts the connection.

You
can configure the reconnection time through the following configurations.

You
need to set the values of the configurations inside the consumer element. For
example:

<Consumer>
         <Name value="Consumer_1"/>
         <Channel value="Channel_1"/>
         <Dictionary value="Dictionary_1"/>
         <XmlTraceToStdout value="0"/>
         <ReconnectMaxDelay value="2000"/>
         <ReconnectMinDelay value="1000"/>
</Consumer>
