Strange defunct process when running Admin server

Hi All,

I have noticed a strange defunct process when I am running the Admin server:

root      6907  0.0  0.5  3184 1392 ?        Ss   Jul03   0:00
./uxwdog -d /opt/fedora-ds/admin-serv/config
root      6908  0.0  2.4 19784 6180 ?        S    Jul03   0:00  \_
ns-httpd -d /opt/fedora-ds/admin-serv/config
root      6909  0.0 10.6 673668 27320 ?      S    Jul03   0:01      \_
ns-httpd -d /opt/fedora-ds/admin-serv/config
root      6910  0.0  0.0     0    0 ?        Z    Jul03   0:00        
 \_ [netstat] <defunct>

Do you have the same problem? Any clue?

Thanks.
Sam
