Hi dev5andhalf,
Thanks for reaching out, We have seen this in the past when a transaction has been POSTed too closely to the previous POST request however would you please be able to create a support request with us HERE and send us a full HTTP trace (including request and response headers, URI and message body/JSON) for the request that is returning the error? The information we are looking for is shown on our
