You don't need all that stuff if you are not on ESX 6.5. So no need to
try to edit those values. And if you upgrade to 6.5 eventually, just use at
least 6.5u1, then you are safe.

Right. But it's a big company and I can't influence when or how ESX gets upgraded.
I can only prepare my VMs for their new lives in this hard, cold, virtual world; and this
was the first attempt with Debian 9.2 on the current VMware release. Results were bad.

If I am doing my job OK, that VM will never once be booted in its years-long lifetime. But
if  the boss ever sees that "TCP performance may be compromised" message on a
production server, or if it ever kills or cripples the OS or apps, I will have a very personal
problem very rapidly.

It's really more about sociology than about computer science.

Sigmentation fault. Core dumped.
