We found a user code which was raising a divide-by-zero trap. That trap would lead to XPC connections between system-partitions being torn down due to the die_chain notifier callouts it received. This also revealed a different issue where multiple callers into xpc_die_deactivate() would all attempt to do the disconnect in parallel which would sometimes lock up but often overwhelm the console on very large machines as each would print at least one line of output at the end of the deactivate. I reviewed all the users of the die_chain notifier and changed the code to ignore the notifier callouts for reasons which will not actually lead to a system to continue on to call die().
