When does a deadlock occur?

When the locks are accessed in wrong order. Basically one thread picks lock A first and lock B after, while at the same time another thread picks lock B first and lock A after. This can be solved by comparing the participating objects system hashcodes and re-ordering the locks accordingly.

When a thread that has acquired an lock on a particular resources for its task execution and at the same time when an another thread wants to access the same resources for its task execution then at that situation deadlock occurs.

Do you have a question about Elastic? Don't ask just anyone for information, ask an employee from Elastic. They're all waiting at Rooftop Slushie.
