RTO EMA C++: Flood of the same update message

Frederic

The client was receive large number of the same 'UPDATE' message. What's the possible cause if technical reason? (The time is GMT+8 in the attached picture)

Hi @Frederic

I cannot think of an obvious EMA misuse that would result in the above scenario - the data is would be as sent by and received from the server.

Please check the Tick History, otherwise discuss with the RTO team to see if they can explain.

37 times of the same 'UPDATE' message. I will also go to the RTH raw report if some finding. But this topic here is only for the possible tech reason or if some misuse of EMA API if you know.

Yes I guess there is some coding problem in client's code

Is the multiple sending of the same UPDATE message by design (e.g., in poor network environment, to guarantee the message delivery, at-least-once semantics)?

Hi @Frederic

I cannot think of an obvious coding problem that would cause the above issue?

Is it happening all the time - or was it a one-off?

Hi @Frederic

I am not aware of any such design - never seen the above scenario before.

sometimes, not always, but can be observed every 2 days a time.

Please check with RTO team and/or the Content team to identify if the RTO is somehow sending these updates or the source data vendor
