Watson Natural Language Understanding Connector

Troubleshooting
Error message: "Too many requests"
Possible cause
You have exceeded the usage limits for concurrent API requests. The default limit is 30 concurrent requests, but this limit can decrease when the service is experiencing heavy traffic.
Proposed action
To reduce the impact of reaching the API speed limits, develop your app with the following in mind:
- Extract only the data you need.
- Reload one Watson-based application at a time.
- Make sure that loops in your script that make API calls don't lead to infinite loops.
