comment fb-dimm without ecc
my question is "are all fb-dimm ecc-protected or not". While it is possible to fb-dimm to be nonecc, it is very unlikely.

comment fb-dimm without ecc
It sounds like theory, but what is in real life? I just checked online market and there are 405 FB-DIMM with ECC and no FB-DIMM without ECC. So, in real life there is no (or almost no) nonECC FB-DIMM, is it?

comment Opened 5GB text file in Pico Text Editor, server crashed, SSH no reponse, pinging works
is it x86 server? How much swap was here? What is usual memory usage on this server? Is there any services you can check besides ping? (ping is in-kernel service.) You can try to do nmap scan to find any

nasa.gov resolves to Akamai because NASA uses Akamai DNS (nameservers), check NS records.
