Concurrent Registrations is the number of registrations the system can hold in memory at one time.
The maximum number of Concurrent Registrations per Form is 500 per Form, per server, in your POD.
When the maximum is met on a Form, subsequent Registrations will receive a notice that reads "Please wait; the page will be automatically resubmitted."
The system will re-submit the request every 15 seconds until space opens up for registrations to proceed.
Troubleshooting & Tips
If you anticipate a large rush of Registrations as soon as the Form goes live, alert Certain Support at least 3 business days ahead of time.
Certain Support will notify the DevOps team so they can monitor the system and ensure it has the resources necessary to accommodate the increased number of Registrations for the Event.
Change the value for Inventory Timeout on Incomplete Registrations.
Navigate to Plan > Configure > Options > Global Settings.
Set a low value (5 or 10 minutes) for "Incomplete registrations count against Capacity/Inventory for ___ minutes after their last modification."
By default, the system sets this at 5 minutes.
If you need to increase this value, try to keep it as low as possible.
The smaller this value is, the faster Registration slots will become available.
If the error persists on your Forms, contact Certain Support so that they can assist in troubleshooting.
