Trouble with RRDTool and updated uClibc

[Devil-Strike]

Thanks, I found the reason :-)

You must change the cron setting to run the script each minute. Edit /opt/etc/crontab and change setting from "*/5" to "*/1"

Old setting:
*/5 * * * * admin nice /opt/bin/rrdtool.sh >> /opt/var/log/rrdtool.log 2>&1

New setting:
*/1 * * * * admin nice /opt/bin/rrdtool.sh >> /opt/var/log/rrdtool.log 2>&1

i have putting that line there already, but not working:

here is what in crontab

SHELL=/bin/sh 
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/opt/bin:/opt/sbin:/opt/usr/bin:/opt/usr/sbin 
MAILTO="" 
HOME=/ 
# ---------- ---------- Default is Empty ---------- ---------- # 
# Syntax for lines is : minute hour day month dayofweek command #
