PM stuck at the PM upload from partial number of eNBs.
this issue i have analyzed, but can not give a solution. need to think more.
就是这一点点思考能力有待提高哟。
现在很多问题我都能ROOT CAUSE,但是基本上提不出解决方案。
•Each action in a thread happens-before every action in that thread that comes later in the program's order.
•An unlock (synchronized block or method exit) of a monitor happens-before every subsequent lock (synchronized block or method entry) of that same monitor. And because the happens-before relation is transitive, all actions of a thread prior to unlocking happen-before all actions subsequent to any thread locking that monitor.
•A write to a volatile field happens-before every subsequent read of that same field. Writes and reads of volatile fields have similar memory consistency effects as entering and exiting monitors, but do not entail mutual exclusion locking.
•A call to start on a thread happens-before any action in the started thread.
•All actions in a thread happen-before any other thread successfully returns from a join on that thread.
