Hello...in my eBay .Net client application, I need to call the GetSellerTransactions many times per day as required to avoid re-uploading duplicated content (especially listing images, which are the most expensive to upload). We are lately experiencing some exceptions of this type (this is the internal log of the eBay sdk library):

HTTP Status 500 -

For your further information, we perform batches of 30 listings per call, until the whole set is returned (the former figure was 200 listings per call and the exception was by far more frequent, so we tried to lower the size of the single batch). To my understanding, there is a chance that one of the load-balanced servers that are serving this particular Api call is in a faulted state, but this is just a guess from the excpetion evidence. Please find the time to have a look at the problem since it is proving quite annoying for us, because our client app is continuously reporting exceptions and when this happens the listing upload procedure cannot proceed cleanly. Thank you very much in advance. The Lordgun ebay store staff-
