cron is ignoring lines...
 
My current crontab looks like:

[root@sda03 ~]# crontab -l
0 0,8,16 * * * /opt/CMTSCheck/bin/GrabCMData.sh
37 * * * * /opt/CMTSCheck/bin/RegStateUpdate.sh
1 1 * * * /opt/CMTSCheck/bin/DropOldTables.sh

For some reason, the only thing that will execute is the middle line... Any idea why?

[root@sda03 ~]# grep GrabCMData /var/log/cron | wc -l
0
[root@sda03 ~]# grep DropOldTables /var/log/cron | wc -l
0

This is on a RH5.1 system with crontabs-1.10-8 installed.

Am I doing something wrong?

Are all of them executable? Check with ls -l.

Any message in the mail box of the crontab's owner?

Yes, they are all executable, and exist. There are no messages in the crontabs mailbox...

[root@sda03 ~]# ls -lah /opt/CMTSCheck/bin/GrabCMData.sh
-rwxr-xr-x 1 501 20 1.2K Apr 6 13:51 /opt/CMTSCheck/bin/GrabCMData.sh
[root@sda03 ~]# ls -lah /opt/CMTSCheck/bin/RegStateUpdate.sh
-rwxr-xr-x 1 501 20 1.8K Mar 31 22:00 /opt/CMTSCheck/bin/RegStateUpdate.sh
[root@sda03 ~]# ls -lah /opt/CMTSCheck/bin/DropOldTables.sh
-rwxr-xr-x 1 root root 524 Mar 30 15:41 /opt/CMTSCheck/bin/DropOldTables.sh

What about redirecting standard output and standard error to a file? Put the current date in the filename so that you know when the file has been created and if the cron job has run at the proper time:
Code:
0 0,8,16 * * * /opt/CMTSCheck/bin/GrabCMData.sh > /opt/$(date +\%Y\%m\%d\%H\%M)_GrabCMData.log 2>&1
37 * * * * /opt/CMTSCheck/bin/RegStateUpdate.sh > /opt/$(date +\%Y\%m\%d\%H\%M)_RegStateUpdate.log 2>&1
1 1 * * * /opt/CMTSCheck/bin/DropOldTables.sh > /opt/$(date +\%Y\%m\%d\%H\%M)_DropOldTables.log 2>&1
