shell script segment fault when executed by crontab

[Reddragon Wang]

Hi all,
I encounter a problem, program will segment fault when executed in a shell
by crontab.
logs:
start abstract bills Sat Jun 17 15:53:01 CST 2006
./startabstract.sh: line 37:  7347 Segmentation fault      abstractsvrd -t
$TABLENAME $billfile
abstartct failed Sat Jun 17 15:53:01 CST 2006

But the shell script is normal when executed manual.
The script like this,

#!/bin/sh
cd /home/bryan/bin
echo start abstract bills `date`

billfile=/data/bill.txt
TABLENAME=t_AdInfo`date  '+%04Y%02m%02d%02H'`

cd /home/bryan/bin
abstract -t $TABLENAME $billfile

The abstract is a program that uses shared memory to compute the bill.

Anyone can help?

Thanks in advance.

bryan
