I'm using Batch requests to execute an FQL queries on the Stream table. The queries retrieve posts from the past few days for all the app user's friends. My application executes about 150K Graph API requests per day (30K each time), but no more that 600 requests in 600 seconds per access token (As Facebook limits the stream API). I sometime receive the following error: (#4) Application request limit reached.
Is there a known limit for Graph API requests per 24 hours / 1 hour ?
