The phrase "not a tty" comes from the "tty" command.
I would look for a script which is trying to put some output directly to the user's terminal.
The script might contain something along the lines:
echo "hello" > "`tty`"
This would work in foreground but create a file called "not a tty" if run from cron or a background process.
It may help you trace the fault if you find out what is in the file called "not a tty".
cat "not a tty" | sed -n l

LAST(1) BSD General Commands Manual LAST(1)
NAME
last -- indicate last logins of users and ttys
SYNOPSIS
last [-n] [-h host] [-t tty] [user ...]
DESCRIPTION
Last will list the sessions of specified users, ttys, and hosts, in reverse time order. Each line of output contains the user name, the tty
from which the session was conducted, any hostname, the start and stop times for the session, and the duration of the session. If the ses-
sion is still continuing or was cut short by a crash or shutdown, last will so indicate.
-n Limits the report to n lines.
-h host Host names may be names or internet numbers.
-t tty Specify the tty. Tty names may be given fully or abbreviated, for example, ``last -t 03'' is equivalent to ``last -t tty03''.
If multiple arguments are given, the information which applies to any of the arguments is printed, e.g., ``last root -t console'' would list
all of ``root's'' sessions as well as all sessions on the console terminal. If no users, hostnames or terminals are specified, last prints a
record of all logins and logouts.
The pseudo-user reboot logs in at reboots of the system, thus ``last reboot'' will give an indication of mean time between reboot.
If last is interrupted, it indicates to what date the search has progressed. If interrupted with a quit signal last indicates how far the
search has progressed and then continues.
