Hi
I continue to investigate this problem by turn on the log of "Group
Management Service", I found some error logs on "FailureNotification", I
don't know if it is the root cause the timer automatic migration failure.

Does it mean the callback failed to perform the timer migration when it got
the SuspectedFailureNotification?
