Hi @Bruno.Leal
Are you performing any pacing of the Posts to the RCC / are they spread out over a time period or are you sending PostMsgs for all 11,000 RICs in one single tight loop etc?
Also, please see the following posts related to another scenario when someone published data quicker than RCC could process - causing Tunnel buffer exhaustion.

Exception in Access/Impl/Thread.cpp - RCC (Refinitiv Contribution Channel) EMA C++

in EMA
Hi Community
I am working on an automation that is able to contribute daily a considerable amount of RICs, we talking about more than 11.000 RICs with 6 fields each one.
Taking as a basis this sample, I was able to build and contribute data to a small number of RICs. However when I try to run it using whole range of RICs that I have, I get an EMA Exception Handler error in the middle of execution.
As you may see bellow, onAckMsg function is returning proper response.
After that, I get bellow Exception.
How can I fix it? or how could I investigate this expection?

Hi @Bruno.Leal
If you are able to recreate this issue reasonably often, I would recommend you try the latest version of the Real-Time SDK. If you are already using the latest version or the issue continues to occur once you upgrade, then my recommendation would be for your contact Developer Support so they can help you diagnose this issue offline in more detail.

Hi @Bruno.Leal
Also, please refer to the section of the tutorial which talks about the Maximum message rate and the RCE:MaxMessagesPerSecond - are you observing this limit?

I'm performing those posts in batch less than 500 RICs by loop. And the next lot is only called when we receive all AckMsg from previously sent batch. Other care I took it was adding a sleep function of 5 seconds among each loop, even so I am still getting that Exception.
The weird part is not always that Exception happens and I'm not able to figure out the root cause.

Yes, I am! For me it's appearing 1,000 RICs per second.
