You can detect a DEADLOCK event-type using the AppDynamics REST API. Details about the deadlock are in the Details tab.

#Deadlock in java code#

To examine a code deadlock, d ouble-click the deadlock event in the events list and then click the Code Deadlock Summary tab. The following list shows two deadlocks in the ECommerce tier. Select Code Problems (or just Code Deadlock) in the Filter By Event Type list to see code deadlocks in the Events list. Two threads may wait for each other to signal an event.The context in which they are being called (for example, from within a callback) is not correct.In multi-threaded development environments, it is common to use more than a single lock. You can find deadlocks and see their details using the Events list or the REST API.

We verified 13 libraries to be free from deadlock, and found 14 distinct deadlocks in 3 libraries. We implemented our analysis and evaluated it on 18 libraries comprising 1245 kLOC. Cycles in the graph indicate deadlock possibilities, and our tool reports all such possibilities. This graph represents the order in which locks are acquired by the library. Our flow-sensitive, context-sensitive analysis determines possible deadlock configurations using a lock-order graph. Our goal is to determine whether client code exists that may deadlock a library, and, if so, to enable the library writer to discover the calling patterns that can lead to deadlock. To this end, we propose a method for static detection of deadlock in Java libraries. Library writers wish to provide a guarantee not only that each procedure in the library performs correctly in isolation, but also that the procedures perform correctly when run in conjunction.
