We all agree that a major responsibility of Scrum Master is to remove impediments. But sometimes I have seen each and every problem is often mistreated as impediment and is expected that scrum master should be solving it on priority. Few examples are :
1. Team member is unwell/on unplanned leave
2. Tool licence expired
3. Non availability of PO to resolve doubts of development team
4. Skill set issues to solve a problem
5. Environment went down/Server crashed.
6. Dependency on someone outside the scrum team
