The process of Apache can not be killed on multi-CPU on Solaris 9

Question

Hi All,
We have the program kill [process number] and kill -p [process number] on Solaris 9 and the Apache process is alive
more than 10 seconds. A user saw the message like "Cannot stop Administration Server. Please kill process $hpid manually and
try again."
We are using 1.3.19-rev2 of Apache.
Here is the extraction from our shell script.
pidfile="./WebServer/logs/httpd.pid"
if ($ps | grep "$hpid" >/dev/null) ; then kill $hpid ; sleep 10 ; else rm -f ./
WebServer/logs/httpd.pid ; fi
# try again with more force
if ($ps | grep "$hpid" >/dev/null) ; then kill -9 $hpid ; sleep 10 ; else rm -f
./WebServer/logs/httpd.pid ; fi
# give up.
if ($ps | grep "$hpid" >/dev/null)
then
echo
echo Cannot stop Administration Server. Please kill process $hpid manually and try again.
We can reproduce the issue on sun4u Sun Fire V490 (2CPU, 8GB RRAM) , but we can not reproduce Sun blade (1CUP).
If those kind of error was barely happening on Sun Fire V490 but we can not see the phenomenon on Sun blade .
regards,
