"kern.coredump" is already 1, but I found "kern.sugid_coredump" in
core(5):

	By default, a process that changes user or group credentials
	whether real or effective will not create a corefile.  This
	behaviour can be changed to generate a core dump by setting the
	sysctl(8) variable kern.sugid_coredump to 1.

Since varnishd is run by root then setuid to nobody, this rule will
apply to.  Change kern.sugid_coredump from 0 to 1 then the core file was
generated.

Core file and execute file is in:
