This article explains that the percentage configured on the application rate limit slider also determines the portion of the Org-wide concurrent request limit that the application can consume.

• Okta Identity Engine (OIE)
• Rate Limiting
• Applications

The solution is to be aware of how this setting impacts the entire Org:

• The percentage set on the app rate limit slider also applies to concurrent requests for that specific client or token.
• The concurrency for a specific client or token is calculated using the following formula:

Org concurrency x token Rate Limit percentage = the concurrency this client/token can consume

• Since the concurrency is Org-wide, if one application is configured to consume 100% of the concurrent requests, other applications will be unable to perform concurrent requests.
