If LC_NUMERIC is effectively set to a value that sets non-null thousands separators or that uses comma as the radix character, you need to take extra precautions when working with CSV files that contain numeric strings that represent non-integral values, or integral values greater than 999 or less than -999.
You are right, Don, as always. In his entry posting Aaron stated that his SysAdmin has traced back the problem to the changed LANG-entry in
/etc/environment, so i took it that none of the applicable LC_-variables are defined in his case, because these would have overridden the old as well as the new setting.
Still, its a good idea to explain the interdependence of LANG and LC_ALL the other LC_-variables.
I hope this helps.

locale.conf
LOCALE.CONF(5) locale.conf LOCALE.CONF(5)
NAME
locale.conf - Configuration file for locale settings
SYNOPSIS
/etc/locale.conf
DESCRIPTION
The /etc/locale.conf file configures system-wide locale settings. It is read at early boot by systemd(1).
The basic file format of locale.conf is a newline-separated list of environment-like shell-compatible variable assignments. It is possible
to source the configuration from shell scripts, however, beyond mere variable assignments, no shell features are supported, allowing
applications to read the file without implementing a shell compatible execution engine.
Note that the kernel command line options locale.LANG=, locale.LANGUAGE=, locale.LC_CTYPE=, locale.LC_NUMERIC=, locale.LC_TIME=,
locale.LC_COLLATE=, locale.LC_MONETARY=, locale.LC_MESSAGES=, locale.LC_PAPER=, locale.LC_NAME=, locale.LC_ADDRESS=, locale.LC_TELEPHONE=,
locale.LC_MEASUREMENT=, locale.LC_IDENTIFICATION= may be used to override the locale settings at boot.
The locale settings configured in /etc/locale.conf are system-wide and are inherited by every service or user, unless overridden or unset
by individual programs or individual users.
Depending on the operating system, other configuration files might be checked for locale configuration as well, however only as fallback.
/etc/vconsole.conf is usually created and updated using systemd-localed.service(8). localectl(1) may be used to alter the settings in this
file during runtime from the command line. Use systemd-firstboot(1) to initialize them on mounted (but not booted) system images.
OPTIONS
The following locale settings may be set using /etc/locale.conf: LANG=, LANGUAGE=, LC_CTYPE=, LC_NUMERIC=, LC_TIME=, LC_COLLATE=,
LC_MONETARY=, LC_MESSAGES=, LC_PAPER=, LC_NAME=, LC_ADDRESS=, LC_TELEPHONE=, LC_MEASUREMENT=, LC_IDENTIFICATION=. Note that LC_ALL may not
be configured in this file. For details about the meaning and semantics of these settings, refer to locale(7).
EXAMPLE
Example 1. German locale with English messages
/etc/locale.conf:
LANG=de_DE.UTF-8
LC_MESSAGES=en_US.UTF-8
