No surprise here.

Whatsapp is based in Ejabberd.

Whatsapp has repeatedly documented how they achieve 2-3M connections per node.

I believe they use erlang, but not ejabberd.

Whatsapp uses a modified version of ejabber. Ejabber is written in erlang.

They started with a version of ejabberd of some sort and migrated to more custom components over time IIRC. I can't find the link right now. (Keep in mind that ejabberd is written in Erlang.)
