VMKERNEL-ZDUMP.FRAG files in var/core

[hendersp3]

I have a bunch of these in var/core.  I always thought this was a core dump that remained fragmented for some reason. When I pull support bundle it stays this way and a zdump file is not created.  Am I mistaken about what these are? 

vmkernel-zdump.1.FRAG-00000  vmkernel-zdump.2.FRAG-00020

vmkernel-zdump.1.FRAG-00001  vmkernel-zdump.2.FRAG-00021

vmkernel-zdump.1.FRAG-00002  vmkernel-zdump.2.FRAG-00022

vmkernel-zdump.1.FRAG-00003  vmkernel-zdump.2.FRAG-00023

vmkernel-zdump.1.FRAG-00004  vmkernel-zdump.2.FRAG-00024

vmkernel-zdump.1.FRAG-00005  vmkernel-zdump.2.FRAG-00025

vmkernel-zdump.1.FRAG-00006  vmkernel-zdump.2.FRAG-00026

vmkernel-zdump.1.FRAG-00007  vmkernel-zdump.2.FRAG-00027

vmkernel-zdump.1.FRAG-00008  vmkernel-zdump.2.FRAG-00028

vmkernel-zdump.1.FRAG-00009  vmkernel-zdump.2.FRAG-00029

vmkernel-zdump.1.FRAG-00010  vmkernel-zdump.2.FRAG-00030

vmkernel-zdump.1.FRAG-00011  vmkernel-zdump.2.FRAG-00031

vmkernel-zdump.1.FRAG-00012  vmkernel-zdump.3.FRAG-00000

vmkernel-zdump.1.FRAG-00013  vmkernel-zdump.3.FRAG-00001

vmkernel-zdump.1.FRAG-00014  vmkernel-zdump.3.FRAG-00002

These definitely are PSOD crash dumps but, in a fragmented state. What is the version and build number of ESXi? Are these files empty (run <ls -lrht> from within /var/core directory)? If you intend to open up a support ticket, they would be able to reconstruct the fragments.

Thanks for your reply.  It's 6.5 build 7388607.  They are not empty.
