JavaScript/OData polling causes 500 Internal Server Error

Hi,

I have implemented an html page which polls various Dynamics CRM records via JavaScript and the OData interface.

In my test environment this approach works well.

In Dynamics CRM Online, however, the repeated OData-ajax calls return errors: 500 Internal Server Error, Generic SQL error, error code -2147204784.

I wonder if there is a limit on the allowed frequency of OData requests (per second / minute).  If so, what is the limit? Where can I find documentation about this limit?

If my guess is wrong and the problem is not related to the polling frequency, what are other possible reasons for the error?

Thanks!

Best regards,

Johannes Riemer.
