NOTE: MISSING "root" after the time spec.
*/3 * * * * root /usr/lib64/.....
This is the "new" way of doing it, using a feature of new versions of cron
to scan a directory to get the cron information.
The old style method would be:
crontab -l > /tmp/afile$$
echo '*/3 * * * * /usr/lib64/...' >> /tmp/afile$$
crontab /tmp/afile$$
rm /tmp/afile$$
The "new style" is much more suitable for scripting; in particular you can
create RPMs that magically drop entries into the cron.d directory.
