Attached the screenshot when deadlock happen, the **SyncArraryQueue** is the same as **DispatchQueue** mentioned above. The **wrap_dispatch_sync** is blocked by Disptachqueue.async as async is set as a barrier for **SyncArraryQueue**. And the async task in SyncArraryQueue is pending as the GCD has reach the thread limitation. In normal case, the deadlock should not happen.
