Cron not working

Hi,
It is SLES 10.3 VM. Suddenly cron stopped working on this and I am not able to figure out, where it is failing. It is not running with even root. I gave a simple job of redirection of 'date' command, that also doesn't work. Can somebody help me to fix this ?

vmprdt23:~ # ps -ef | grep -i cron
root     24421     1  0 16:56 ?        00:00:00 /usr/sbin/cron
root     29262 28708  0 19:36 pts/0    00:00:00 grep -i cron
vmprdt23:~ # /etc/init.d/cron status
Checking for Cron:                                                    running
vmprdt23:~ #
vmprdt23:~ # crontab -l | grep -i date
37 19 * * * /bin/date >> /var/tmp/date_0
vmprdt23:~ #

Below is from /var/log/messages

Looks like you missed the scheduled execution time by a second when reloading the crontab ; it will now execute the next day.

It was not missed. I tried it multiple times and it never ran. May be I picked wrong example above.

Is that entry correctly terminated with a <newline> char?

Yes, I confirmed that entry is correctly terminated. Still it is not fine.
