+    1.  [Eiger] Stop command freezes server 
+        It is apparent in large detectors.
+
+        For example, if module A got a "stop" during an acquisition, 
+        it stops to an 'Idle' state. If module B gets a "stop" before an 
+        acquisition, it will return it is in 'Idle' state and continue 
+        to start the next acquisition, but module B then waits for "ready
+        for trigger" synchronization from module A, which it will never get.
+        
+        Since module B missed the asynchronous stop command, the workaround
+        in the client is to send another "stop" command (upto 10 retries) 
+        till it returns Idle.

+        Stop results in different frame numbers
+        A "stop" command will also now check for inconsistent 'nextframenumber'

+        all start with the same frame number for the next acquisition.
