WebChat 429 errors during JMeter load test

Quick question about the WebChat WebSocket connection limits. I am running a JMeter script to simulate 500 concurrent chat sessions. The connections establish, but after 100 users, the backend starts dropping messages with this error:

429 Too Many Requests

The API docs mention rate limits for REST calls, but this is a persistent WebSocket. Is there a specific threshold for simultaneous active chats per org, or is my JMeter thread group configuration incorrect?

If I remember correctly, this is not a WebSocket limit but a rate limiting issue on the REST API calls that JMeter might be making to establish or manage those sessions. Check if your script is sending excessive heartbeat or status update requests. The Performance dashboard often shows spikes in queue activity during such tests, indicating the system is processing too many control signals rather than conversation data.
