Hey @Kal_Lam, in this case the problem is likely not caused by the number of submissions, but rather something else about the project that was putting exceptional stress on the servers.
@healthsectionhooghly, if you are running any kind of automated task to retrieve data or otherwise access the API, please be sure to limit its rate of requests to something reasonable. For example, please do not regenerate exports of your entire dataset more than once every 5 minutes.
