To keep the AACT database stable and available for everyone, we have started limiting the number of simultaneous database connections per account. Some automated tools and scripts were opening multiple connections and not closing them properly. Because this is a shared public resource, we encourage everyone who connects programmatically to make sure connections are closed when no longer in use. The current limit is 10 concurrent connections per user account. This helps ensure fair and uninterrupted access to the AACT database for all users. If you have a special use case and need a higher limit, please reach out to us using the Contact Us form and let us know what you need.
