V$GC_ELEMENTS_WITH_COLLISIONS

This is a Real Application Clusters view. Use this view to find the locks that protect multiple buffers, each of which has been either force-written or force-read at least 10 times. It is very likely that those buffers are experiencing false pings due to being mapped to the same lock.
