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
Perhaps the crudest form of deadlock detection and recovery is the watchdog timer. In event of a deadlock, the timer will elapse (deadlock detection),and reboot the system (recovery). As a last ditch safety net for very infrequent or as yet undiscovered deadlocks this is acceptable. ...
There are several methods for deadlock detection. One approach is to periodically check the system's resource allocation state and look for circular wait conditions. Another method involves using wait-for graphs to analyze the relationships between processes and resources. ...
To address this need, I've built a sample wrapper for the .NET System.Threading.Monitor class that includes deadlock detection capabilities. As with Monitor, my DdMonitor class provides Enter and Exit methods, and under the covers it delegates to the equivalent methods on Monitor. However, it...

Deadlock is a situation in database management systems (DBMS) where two or more transactions are waiting for each other to release resources, leading to a permanent blocking state. To prevent deadlocks, there are several methods such as Deadlock Avoidance, Deadlock Detection, and Deadlock Prevent...
