I'm writing an app to translate XLIFF content automatically via Bing Translator. I iterate over the <trans-unit> elements, pull out the <target> element value, and pass it to Bing Translator using the Translate method. The first 494 seem to work fine and then the service call stops working for a period of time. I've tried having my application sleep for 10 seconds and get a new access token, but this doesn't seem to solve the problem. I've tried resetting the connection before it gets to 5000 characters translated. Without explanation, the service stops working for a while, then starts working again...then fails again...then starts up again.
Is there some kind of characters-per-minute limit? I've seen that there is a 10-minute limit on access tokens and I know there is a max limit on characters per request, but these should all be well below that limit.
Thanks for any help that anyone can offer.
Here is a log of when the service fails. If there is no entry, such as 1 through 494, the translation has succeeded.
