Let me know what debugging info you need. My python isn't good enough to see what the script is looking for. Running as root, so should have full permissions.

Can you show the output from these commands:

$ cat /proc/sys/kernel/osrelease
$ ls -l /proc/$$/smaps

[plutocrat]

Sure.

cat /proc/sys/kernel/osrelease
4.4.0-116-generic
ls -l /proc/$$/smaps
-r--r--r-- 1 root root 0 Mar 28 15:55 /proc/8551/smaps

I can confirm the warning has disappeared in this version.

But no further output after the final lines, where the warning formerly appeared:
