There following issues here:
Whenever Galera BF (brute force) transaction decides to abort conflicting transaction it will kill that thread using thd::awake()
Whenever replication selects a thread as a victim it will call thd::awake()
User KILL [QUERY|CONNECTION] ... for a thread it will also call thd::awake()
Whenever one of these actions is executed we will hold number of InnoDB internal mutexes and thd mutexes.
