Help: RMDS client data blocked over 10000 retries

Hello All,

May I ask if anyone has seen such log errors generated before?

RMDSThread error: Channel Stucked, RMDS client data blocked over 10000 retries, continue retrying

The stack trace as follows:

 java.lang.RuntimeException: RMDSThread error: Unexpected spsc channel stuck

Thinking where to start investigations.

Thank you very much, in advance!

It should be a message generated by the application. I am not sure what it means.

You can check the RFA configurations. 10000 is the default value of the connectionTimeout configuration.

Moreover, from the call stack, the exception happened in the application code.

It could be an application error, not an RFA error.

Please contact your developers to verify this error.

Thank you @Jirapongse , the question actually came from the developers themselves.

What are your opinions though?
Because if there are specific points which you think they can check for their code, I can help to get back to them with questions.
