Meanwhile, the latest version is 1.0.1, so updating might be worth a try
(although I don't know of any fixes specific to your issue).

Hrm, this usually sounds like the process invoking node_exporter has not
recognized the exit properly yet. Is this from the start using systemd?
Can you share the unit file?
Or is this from a manual start? Could it be that you had backgrounded
the process using "&" or using Ctrl+Z? If so, try foregrounding it (fg)
so that the shell can properly handle the exit.
You can try to look at what this process was doing lastly by running
cat /proc/53547/stack
But I suspect that it will not lead to anything useful.
I think this may just be a dead process table entry. If nothing helps,
you could reboot. In any case, this shouldn't prevent you from running
further tests (e.g. it should not block the listening port or anything).
Kind regards,
Christian
