Duplicated trade updates received

Hi Elektron specialists,

There is a logic in our application for resilience purposes. For each symbol, we request the refresh message via 2 streams, but the following update shall be coming up only on one stream as described in the following article:

https://developers.refinitiv.com/en/article-catalog/article/how-implement-service-resiliency-ema-consumer-application

The issue looks only appears on LSE market data. For other RICs, we do receive the refresh twice but subsequent updates coming only on one stream.

Could you help take a look at this? Thanks

To verify the problem, you need to enable XML tracing in the EMA. To enable XML tracing, please refer to the EMA configuration guide and search for xmlTrace.

With the XML trace, we can verify messages sent and received by the application and find why the application got the duplicated updates of the LSE market data.
