The rrd subsystem wanted to create a file, env 12 Kbytes, a shells script.

This file is mostly identical for all of us, although some hardware / software differences can make this file a little bit smaller, or bigger.

If fwrite() = "file write" returns a 'false', then these are the classic reasons :
If the file could be opened for writing, and then fwrite failed : not enough space on device ?

and because there was no error checking :

If the fopen() failed - opening /var/db/rrd/updaterrd.sh for 'writing' and it failed, subsequently fwrite will use the not correctly initialized file descriptor, $fd.
fopen can find if the file folder/path "/var/db/rrd/" doesn't exist (yjis would be alarming), the file already exists, but can't be overwritten (not applicable here, root can overwrite root**) or .... no space on device.

** You've mentioned 'sudo'.
This makes me think : are you doing 'root' (admin) only things with a non root user ?
I know, vague question but I guess you get the point.

Yep.. kinda.. trying to go straight to the menu when I ssh in.. without having to type a command I never remember..

I'll have to retrace my steps and see if I can cause it again.. then never do that again lol.
