Can dump files like java core dump, heap dump, snap dump, be deleted? They are occupying lots of space on the server.

Is there any usage of this file? Will anything happen on production servers if i delete these? The files I see are:

heapdump.20158411.1405458303.28470.0001.phd
heapdump.29043851.1394540224.25760.0003.phd
Snap.20110411.143450200.25760.0004.trc
javacore.201457810411.140200.25760.0002.txt

Yes, then can be safely deleted. These are result of dump that have happened sometimes ago. For more information, please have a look at:

You might want to know why your runtime crashed...

You don't need them unless you or your developers want to analyze them to find out what caused the crash. With that being said, I am unsure what the "snap" file is but the heap dumps are safe to remove or move.
