I'm using GCViewer to check some GC logs. ( please check the screenshot below)

Im getting lots of high pauses (red rectangles) which seem to be related to "vm operation events(application stopped...)". These seem to be different from regular and full GC Stops .

* How can I get to know which are the operations which are triggering a stop event? (Is there a JVM flag for this?)
* Are they different from garbage collection? as far as GCViewer goes the Full GC Pauses + GC Pauses != Total Pause
