Is it possible that you are seeing a problem caused by something like
"selinux"? If you have selinux enabled, try disabling it and see if that
improves things... I'm not giving any promises, but certainly something
is not quite right in this setup, and it looks like you have the right
processes running, so that's not the issue.

This is normal for certain builds of Linux - it's because "nash" (or
some other component used by the "initrd") are using statically linked
libraries that use TLS. Since this process disappears before the system
is up and running, I wouldn't worry about it - if you really want to
"fix" it, then you will have to rebuild the component in question that
is in your initrd, and then rebuild the initrd to make use of this newly
built version. But I wouldn't worry.
