- **Circular wait** : there exists a set { P0, P1, …, P0 } of waiting processes such that P0 is waiting for a resource that is held by P1, P1 is waiting for a resource that is held by P2, …, Pn –1 is waiting for a resource that is held by Pn, and P0 is waiting for a resource that is held by P0.
### Methods for Handling Deadlocks
+- Put the system in a situation where the deadlock can be avoided, i.e. Deadlock Avoidance.
- Ensure that the system will never enter a deadlock state.
- Allow the system to enter a deadlock state and then recover.
- Ignore the problem and pretend that deadlocks never occur in the system; **used by most operating systems, including UNIX**.
