Afterwards, a new deadlock detection … WebDistributed deadlock detection is implemented in System R* . In distributed database systems, effective global deadlock detection rely on the the timely propagation of local information from all the sites. However, some sites might be slower in propagating local information. As a result, this might lead to the detection of phantom deadlocks.
