Please post what Operating System and version you are running, the line from crontab, any error messages found in the unix mail for the owner of the crontab, and any evidence you have of the failure which might give folks a clue what to look for.

First impression is that running an interactive process which requires a terminal is not going to work when there is not a terminal context (i.e. in cron). The error messages should support this.

crontab

CRONTAB(1)						      General Commands Manual							CRONTAB(1)

NAME

       crontab - maintain crontab files for individual users (V3)

SYNOPSIS

       crontab [ -u user ] file
       crontab [ -u user ] { -l | -r | -e }

DESCRIPTION

       Crontab	is  the  program used to install, deinstall or list the tables used to drive the cron(8) daemon in Vixie Cron.	Each user can have
       their own crontab, and though these are files in /var, they are not intended to be edited directly.

       If the allow file exists, then you must be listed therein in order to be allowed to use this command.  If the allow file does not exist but
       the  deny  file	does  exist, then you must not be listed in the deny file in order to use this command.  If neither of these files exists,
       then depending on site-dependent configuration parameters, only the super user will be allowed to use this command, or all  users  will	be
       able to use this command.

       If the -u option is given, it specifies the name of the user whose crontab is to be tweaked.  If this option is not given, crontab examines
       "your" crontab, i.e., the crontab of the person executing the command.  Note that su(8) can confuse crontab and that  if  you  are  running
       inside of su(8) you should always use the -u option for safety's sake.

       The  first  form  of  this  command is used to install a new crontab from some named file or standard input if the pseudo-filename ``-'' is
       given.

       The -l option causes the current crontab to be displayed on standard output.

       The -r option causes the current crontab to be removed.

       The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables.  After you exit
       from the editor, the modified crontab will be installed automatically.

SEE ALSO

       crontab(5), cron(8)

FILES

       /etc/cron.allow
       /etc/cron.deny

STANDARDS

       The  crontab command conforms to IEEE Std1003.2-1992 (``POSIX'').  This new command syntax differs from previous versions of Vixie Cron, as
       well as from the classic SVR3 syntax.

DIAGNOSTICS

       A fairly informative usage message appears if you run it with a bad command line.
