we have ORACLE database 10GR2 on LINUX server.  I found one thing very wield:

SQL> select count(username) from v$process;

COUNT(USERNAME)
---------------
             99


SQL>select count(username) from v$session

COUNT(USERNAME)
---------------
             16

I check on LINUX system use :

%ps -ef | grep DB01 | wc -l
99

anyone know why only 16 session and have 99 processes?
