Since we are using the fine-grained locking mechanism, I am suggesting to fix this issue with the changes in this PR. The idea is to avoid calling `sa.updateAskRepeatInternal()` in `recoverOnNode()`. I was first trying to move the app lock inside of `updateAskRepeatInternal()` but that doesn't work because this "internal" call is assumed to be app-lock-free.
