Deadlock Recovery

• Process Termination
  =>Abort all deadlocked processes:
  1.)Fast
  2.)A lot of process work is lost.
  =>Abort one deadlocked process at a time and check for deadlocks again:
  1.)More work to resolve a deadlock.
  2.)Better in terms of process work.
  3.)What is a good order to abort processes?
  
• Resource Preemption
  =>what is a good way to select a victim
  =>How can we rollback and then recover from preemption?
  =>How can we protect from starvation

What can the system do if it discovers a deadlock?
