Since this morning I've noticed that some of my uploads are failing because the BatchJob does not return all the AdGroups that are created.

It's actually a test creating 5001 AdGroups, 5001 AdGroupAds and 5001 AdGroupCriteria that we use for our integration tests.

We send 5001 operations to create AdGroup but we get back a response containing 4999 items regarding the creation of the AdGroups.

Other details:

 - the test has been running fine till today for more than 1 year

 - the test contains no operations that may cause an error/violation

 - the response does not contain any error

 - it happens around 30-40% of the times that I run that test 

 - the missing 2 adgroups are actually created and I can see them on the interface

Here's the link to the BatchJob result (I believe the url contains the batchjob id too)  https://batch-job-download-prod-ebe9b43.storage.googleapis.com/109310708/516281235.results.xml?GoogleAccessId=926043054183-rbu1gkdus...@developer.gserviceaccount.com&Expires=1500550621&Signature=Qizy1GALGMf%2BQxlLBLaU6JORNZcF4ha7XQccGO0IL1gyzhbkI7AF7QQJPXQesfYVsCqw5n7oZ4BwmYSZyjo%2BcBvaDzXH7VU53WcpDUBniwI%2F3otyf%2Bp%2Bwc5M1Bd3gkw0kr32xYl%2BGVdtRA%2FFQGmu%2ByQ8acEVTwLL7OxenUfqyWFDM2GYjUFwyDJBYA%2FxF04jI%2BGvOWScqiK%2F8Toeq2GXPfgef0QJgN418f8Syo64VUYatZA%2BH0puo9mzn82orwdDV2Ft2MqHMQAulseuT6KGndOq1mktDF5KKPOXgaX5dwFTQq3wUXxI0Ctt%2FXBPufEhDiTwoT9EQd1ORQ9xA6Zs9g%3D%3D
