10g Listener spawns 2nd Listener

Question

Search Fu not good.
Have any of you experienced a listener spawning a 2nd. listener?
Solarius box - two listener processes - one owned by the other.
Customers started getting tns time out errors.
Thanks,

Hi
Here's a very simple script that solves the problem until the patch can be safely applied:
#!/bin/bash
export ORACLE_HOME=/oracle/product/10.2.0/Db_1/
export ORACLE_BASE=/oracle
export PATH=$PATH:$ORACLE_HOME/bin
export TNS_ADMIN=$ORACLE_HOME/network/admin
export ORACLE_SID=prod01
export EDITOR=vi
PATH=/home/oracle/bin:$PATH
ps -efo stime,pid,user,comm |sort | grep oracle | grep tnslsnr > /home/oracle/tmp_fil
AA=`cat /home/oracle/tmp_fil | wc -l`
NUM=`echo $AA`
# echo "$NUM"xx
if [ "$NUM" == "0" ]
then
lsnrctl start;
elif [ "$NUM" != "1" ]
then
PID=`tail -1 /home/oracle/tmp_fil | cut -b9-16`
kill -9 $PID
echo ' ' >> /home/oracle/chk_kill_lsnr.log
date >> /home/oracle/chk_kill_lsnr.log
echo "Killed duplicate listener process pid="$PID >> /home/oracle/chk_kill_lsnr.log
fi
rm /home/oracle/tmp_fil
