Here we can clearly identify the deadlock situation from the output but in real life applications it’s very hard to find the deadlock situation and debug them. Analyze Deadlock To analyze a deadlock, we need to look at thejava thread dumpof the application, in last post I explained how...

The techniques involved in picking the three basic types of tumbler mechanisms are very similar that an example using the pin tumbler cylinder will serve to illustrate the rest. All picking techniques depend on the slight clearances that must necessarily exist in a mechanism for it to function. ...
Just to fully answer the question I led with: we introduced the deadlock in the section title "What's in a name". In the real life production code, the bug came into existance in almost exactly the same way I described above. We had an existing helper method that took a read lock, ...
But in a complex application with many locks held and released all over the code, deadlock is a real-life problem. A couple of quite realistic example scenarios, that require related but subtly different solutions for reasons we'll discuss in a minute: You have a single read-write data...
Give an example to substantiate your answe When the scheduler overlooks a process that is runnable, this situation is called what? A) Deadlock (B) Livelock (C) Race (D) Starvation (E) This situation cannot happen. Why is synchronization a problem in data communication? Which of...
The psychological effects of this drama are enough to land Six in sickbay and put the baby's life in jeopardy. The whole notion of all of this is predicated on the belief that True Love is what's apparently needed to sustain a Cylon fetus. One scene I thought worked pretty well was ...

To that end, the lock validator must track real locking patterns in the kernel. There is no point, however, in tracking every individual lock - there are thousands of them, but many of them are treated in exactly the same way by the kernel. For example, every inode structure contains a...
