Maybe open a support case for this if you haven’t already so we can take a deeper look. There might be some improvements that could be done.
The requests are stored on disk on the feed-masters and won’t be cleared until the request is fully processed by the ultra pipeline. So, you’ll need enough space to store the queued requests. You’ll also want to reply to the client right away and not wait for processing to finish so that connections are freed up (in other words, use a Copy and one branch sends a response while the other does the actual work).
