Hi, mir is a very nice protocol, and I want to use it for my research. When I use mirbft to implement a state machine, I found that each client has to broadcast the request to every mirnode from the design, and every mir node will run mir to make an agreement on the order of the requests. It works perfectly for a small number of clients, such as 4 clients with 4 mir nodes setup. However, when I increase the number of clients but keep the number of mir nodes, I found that some of mir nodes do not have the payload when committing the request. For example, 16 clients with 4 mir nodes setup, each client has a unique client id, broadcast requests to mir nodes concurrently. In some cases, one or more of the mir nodes report "key not found" either when "Apply" the request or "Commit" the request. Can you please give me a hint on this issue? I am using the reqstore and processor in the mirbft library to handle the request.
