GrainTimer dispose exception when using orleans dashboard

[sc-starman]

Using Orleans Dashboard 7.2.1, when I register Orleans dashboard on the host and on a graceful shutdown I got this exception repeatedly: [11:43:30 ERR] Caught and ignored exception thrown from timer callback for timer GrainTimer.sys.svc.user.95B6CAE6/127.0.0.1:11111@46080769Timer TimerCallbackHandler:[SystemTarget: S127.0.0.1:11111:46080769/sys.svc.user.95B6CAE6/127.0.0.1:11111@46080769@0d73e76f000000002b539dc300000000]->System.Threading.Tasks.Task <Start>b__11_0(System.Object) System.ObjectDisposedException: Cannot access a disposed object.
