In deadlock detection, the operating system considers that a deadlock situation will occur and then it will identify it. No methods for prevention or avoidance of deadlocks are applied here. So, the OS analyses if there is a deadlock. If detected, recovery methods are applied. Deadlocks are ...
In addition to performance problems, programs that rely on complex synchronization are prone to a variety of problems, including deadlock. Deadlock occurs when two or more tasks are waiting for each other to release a lock. Most of the horror stories about parallel programming are actually about...

Deadlock A deadlocked program is one in which all concurrent processes are waiting on one another. In this state, the program will never recover without outside intervention. If that sounds grim, it’s because it is! The Go runtime attempts to do its part and will detect some deadlocks (...
