core dump mostly occurred during PSOD , you can read it.

1. Find the vmkernel-zdump file in the /root/ or /var/core/ directory:
   
   # ls /root/vmkernel* /var/core/vmkernel*
/var/core/vmkernel-zdump-073108.09.16.1
   
   
2. Use the vmkdump or esxcfg-dumppart utility to extract the log. For example:
   
   # vmkdump -l /var/core/vmkernel-zdump-073108.09.16.1
created file vmkernel-log.1

You can read vmkernel-log.1 in notepad++

Hello Baber,

That is a known issue with 6.5. Please find the below VMware KB article. This is an SFCB process on the ESXi host which is crashing not psod. Var/core holds all the crash dumps including vmkernel, vpxa, hostd etc. The dumps which are seeing is related to sfcb

"sfcb-smx: wantCoreDump:sfcb-smx signal:6 exitCode:0 coredump:enabled" error on ESXi 6.5 hosts (2148...

Thanks,

MS
