“Account Locked”

We have an application which downloads large amounts of data (10 files with a total of 5.8GB) using NSURLSession in the background. On iOS 8.3 and iOS 8.4 beta 3 we observed the following- The download sometimes suddenly stalls at around 1.2GB. Seems to happen on fat internet conenction with an iPad Air 2.- If we force terminate the App in this situation it can't be launched again. We have found that the nsurlsessiond is using 100% CPU and that the watchdog ist killing the App just after the launch as it is not responding. Looking at the crash report the creation of the NSURLSession [NSURLSession sessionWithConfiguration:delegate:delegateQueue:] seems to be waiting on a semaphore.This might be related to this post https://devforums.apple.com/message/1128072#1128072.I've attached the crash report below.Any ideas? We have filed this as Bug rdar://21300082Jakob------------------------------------------------------------------------Incident Identifier: 32D98114-3D3C-4C26-BFB5-F2984F6084DECrashReporter Key: 601353

thank you for helping...how long does it take to get a reply from support?my app has been approved and is in the transfer process from the developer to my account... i submitted the tax information & received a message popup stating that iTunes could not verify & would try again, later & would email me if they needed any addtional information...it has been 7 days and i even opened a ticket on the 3rd day... i have not received any email from iTunes other than confirmation of my support ticket...any idea how long the wait time is on this type of issue?thank you, again...------

We have tried Mavericks, Yosemite, and still slow. Considerably slower than PC's accessing the same file system over the WAN. NFS is much faster but unfortunately NFS does not allow you to lock files while editing them. Anyone have a possible solution? Thanks.

In iOS 9 beta 1, there is a Use Side Switch To: preference allowing selection of Lock Rotation or Mute, similar to iPad. As a user, I expect to enjoy this feature as I don't personally have a need to quickly disable the mute feature, but often want to lock my phone in portrait mode when reading. However, I'm noticing two immediate differences that could affect app interaction design, and I wonder if only one is deliberate.1) Rotation lock, when controlled by the side switch, behaves like previous iPhone on-screen controls in that it locks vertically. From a development perspective, that means developers should continue to implement their own controls to force landscape when necessary. YouTube provides a good example of this with their full screen control, whereas many creative apps have only a landscape mode.2) Mute is not available in Control Center, leaving no clear ability to acheive the mute functionality the side switch has toggled since the original iPhone. iPad has h
