    Have you tried to adjust the "max body size"? Seeing people be successful with setting it to 900kb.

    For the Request Concurrency Limit message, please see our Docs related to the Destination here:


    Request concurrency: Enter the maximum number of ongoing requests to allow before blocking.

    This is a user defined setting that you can increase to mitigate this issue.

    Due to Chronicle's Payload Limit, you will need to fine tune the below setting:

    Max body size (KB): Enter a maximum size, in KB, for the request body.

    Somewhere in between 700-900 is a decent value.

    Closer to 900 would likely mean that you could run into the issue though - just not as frequently.
