There are maximum limits for concurrent export requests. Tenable.io applies these limits on concurrent exports to ensure that all customers experience the same level of service. You can have a maximum of two or three active concurrent export requests per Tenable.io customer instance or container depending on which endpoint you are using.
If you submit an API request after the concurrency limit is reached, Tenable.io returns an HTTP response message with a
429 (Too Many Requests) status code. The response also includes a
retry-after header element that specifies the number of seconds to wait before retrying.
