For some reason the SFTP child process terminates immediately after being started:
Check if the program /usr/libexec/openssh/sftp-server really exists, and is runable by regular users.
I've had the hardest time getting my Windows users (technically proficient users who grew up with VAX.VMS systems) to abandon FTP and TELNET for SSH and SFTP/SCP. It's getting to the point where I'm getting seriously angry at them for being "stupid". With that little bit of complaint aside after... (1 Reply)

sftp-server
SFTP-SERVER(8) BSD System Manager's Manual SFTP-SERVER(8)NAME
sftp-server -- SFTP server subsystem
SYNOPSIS
sftp-server [-ehR] [-f log_facility] [-l log_level] [-u umask]
DESCRIPTION
sftp-server is a program that speaks the server side of SFTP protocol to stdout and expects client requests from stdin. sftp-server is not
intended to be called directly, but from sshd(8) using the Subsystem option.
Command-line flags to sftp-server should be specified in the Subsystem declaration. See sshd_config(5) for more information.
Valid options are:
-e Causes sftp-server to print logging information to stderr instead of syslog for debugging.
-f log_facility
Specifies the facility code that is used when logging messages from sftp-server. The possible values are: DAEMON, USER, AUTH,
LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The default is AUTH.
-h Displays sftp-server usage information.
-l log_level
Specifies which messages will be logged by sftp-server. The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1,
DEBUG2, and DEBUG3. INFO and VERBOSE log transactions that sftp-server performs on behalf of the client. DEBUG and DEBUG1 are
equivalent. DEBUG2 and DEBUG3 each specify higher levels of debugging output. The default is ERROR.
-R Places this instance of sftp-server into a read-only mode. Attempts to open files for writing, as well as other operations that
change the state of the filesystem, will be denied.
-u umask
Sets an explicit umask(2) to be applied to newly-created files and directories, instead of the user's default mask.
For logging to work, sftp-server must be able to access /dev/log. Use of sftp-server in a chroot configuration therefore requires that
syslogd(8) establish a logging socket inside the chroot directory.
