We will introduce a global rate limiting mechanism in the OCPP handler to protect system stability during high-load scenarios. The feature prevents floods of new connections and boot-related messages from degrading the performance of already connected chargers.
OCPP Connectivity
- Added global rate limiting to protect against floods of new connections and boot-related messages that could degrade performance for already connected chargers.
- In high-load cases, new connection attempts may receive an HTTP 429 Too Many Requests response. Production chargers are unaffected as they automatically retry later.
- Automated end-to-end tests without WebSocket retry handling may occasionally fail due to this change. Updating test configurations with retry logic is recommended.
This change will be applied on a scheduled window on 3.9.2025.
