Periodic crashes are occurring in areas where a frequent number of dispatches to the Default QOS queue are occuring. A search about this identifier generally says that there are too many items submitted to this queue and that iOS will not run the method, and that it can lead to a crash. In this particular case the crash comes from a method in the dispatch, "... unrecognized selector sent to instance ..."That crash reason is fairly consistent, but random in where it occurs and when. Can someone provide a definitive definition and possible consequences of the overcommit, and suggestions beyond looking for Zombies to isolate hwo the overcommmit is occurring and what that may be breaking?

It has been several hours and the device will not power off or force restart. It recognizes the attempts and puts a message up below the progress bar indication it will restart when the update is complete. Has anyone else seen this, and what suggestions for recovering from this?

This tool to do tcpdumps from the devices is missing from Xcode 11. Does anyone know if Apple is pulling support for it or if this is just a beta 1 hiccup? Or is there an alternative to capturing the network stream in Xcode 11/xOS 13?
