OK, after using strace to track this down, we found out the cause was
the contents of the $HOME/maya directory was causing the error.
So the solution was to rename away the ~render/maya directory to something else,
then the renders ran fine. So while ssh'ed in as the user "render":
mv ~/maya ~/.junk
..and from then on the renders ran OK.
It seemed like even though the ~/maya directory has subdirs that have version specific
subdirs (2014 vs. 2017), somehow the 2017 dir still had paths pointing to 2014.
It was great that you could replicate all this from ssh, finding that it worked
in the "root" account, but failed in the "render" account.. that really led us
to the solution quickly, as typically differences between accounts boils down to:
o Environment variables
o Permissions
o Home directory
We ruled out the first two pretty quickly, and ended up with the last one as being
the culprit, since Maya likes to look for and create files in the user's home directory,
even when network rendering.
