Segmentation fault calling an oracle db status script

Question

HI,
I have a problem on a OEL 5 cluster with an Oracle 10.2.0.3 in active/passive environment (not RAC).
When the Oracle Cluster service script checks the status of the service sometimes I have segmentation fault error.
The script is:
#!/bin/sh
# Cluster service script to start, stop, and check status of oracle
set -xv
case $1 in
start)
su - oracle -c /home/oracle/startdb.sh
RetVal=$?
stop)
su - oracle -c /home/oracle/stopdb.sh
RetVal=$?
status)
su - oracle -c /home/oracle/statusdb.sh
RetVal=$?
esac
set +xv
exit $RetVal
The error log of the executing the "status" part of the script is:
+ case $1 in
+ su - oracle -c /home/oracle/statusdb.sh
/usr/local/sbin/oraclust.sh: line 16: 6779 Segmentation fault su - oracle -c /home/oracle/statusdb.sh
+ RetVal=139
This script is executed every 30 seconds but I have the error once every 10 hours.
What could it be?
Many thanks.

hi,
here is the script /home/oracle/statusdb.sh:
#!/bin/sh
# Script to CHECK the Oracle Database Server Status.
ORACLE_RELEASE=10.2.0
export ORACLE_SID=mysid
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/${ORACLE_RELEASE}/db_1
export LD_LIBRARY_PATH=${ORACLE_HOME}/lib:$LD_LIBRARY_PATH
export PATH=$PATH:${ORACLE_HOME}/bin
${ORACLE_HOME}/bin/sqlplus / as sysdba << EOF
whenever sqlerror exit sql.sqlcode;
whenever oserror exit failure;
set pagesize 0;
set feedback off;
set wrap off;
set heading off;
UPDATE clustmon.clst_chk_tbl SET status = 'ok';
commit;
quit;
EOF
exit $?
thanks.
