Deadlock
A classic problem in concurrent programming in which two or more processes or threads are permanently blocked because each holds a resource the other requires. Deadlock detection and prevention are critical concerns in operating systems and database systems.

In financial payment pipelines, when acquiring locks on multiple rows, they should be acquired in a globally deterministic order (such as ascending by account primary key ID) to prevent deadlocks.
Deadlock refers to a state in which a group of vehicles or resources falls into circular waiting and none of them can make further progress.
Collision avoidance alone cannot eliminate the deadlock problem—a system can prevent physical collisions yet still permit inefficient waiting patterns or deadlock.
如果检测到环（循环等待），协调层需要触发告警或强制中断其中一个任务，否则整个系统会陷入死锁。
A livelock is when all parties are continuously acting but their actions cancel each other out so the system makes no progress, while a deadlock is when all parties are waiting for each other and the system is completely stuck.
Orchestrators that can loop make multi-agent systems prone to distributed system pathologies such as livelocks, deadlocks, and infinite retries.
Deadlock requires four necessary conditions (Coffman conditions) to be simultaneously satisfied: mutual exclusion, hold and wait, no preemption, and circular wait — breaking any one of them can prevent deadlock
Deadlock refers to a situation where a process is completely unable to make progress
Deadlock refers to two or more robots waiting for each other to give way, forming a circular wait that causes a complete stop; livelock refers to robots continuously adjusting but forming a cycle of periodic ineffective movements.
