The targeted queue has reached its maxSize limit. Once the queue reaches the limit, new requests to queue calls using <Enqueue> will be rejected.
A full queue can indicate higher <Enqueue> volume, longer queue times, or an incorrectly configured queue's maxSize.
A queue's maxSize can be adjusted to a maximum of 5000. Use the Queue API to identify the current maxSize and adjust accordingly.
If a waitUrl is provided for <Enqueue>, the parameters MaxQueueSize and CurrentQueueSize are included in the Webhook request to the waitUrl. Your application can use this information to determine queue capacity and adjust max queue size via the API.
If the queue is already configured for the maximum allowed queue size (5000), one possible workaround is to create multiple queues and distribute the <Enqueue> requests between them.
