What are the conditions for a deadlock and are they fulfilled?

(there are 4 conditions)

- Mutual Exclusion condition

Each resource is either currently assigned to exactly one process or is available.

- Hold-and-wait condition

Processes currently holding resources that were granted earlier can request new resources

- No-preemption condition

Resources previously granted cannot be forcibly taken away from a process. They must be explicitly released by the process holding them

- Circular wait condition

There must be a circular list of two or more processes, each of which is waiting for a resource held by the next member of the chain

We discussed options to deal with deadlocks. Discuss al of them and if/how can/cannot be applied to this situation

- Ignore it (maybe it ignores us too...)

- Detection and Recovery

- Avoidance

- Prevention
