[logging processes] Too many or Not too many?

[Pae Choi]

Tomcat v7.0.25
CentOS 5.7 32bit

Running the tomcat without any webapp deployed, the system shows about 
38 processes
related to logging. Why that many and what are they logging about?
I see some of logging under the "$CATALINA_HOME/logs" folder and they 
seemed to be
reasonably needed. But what others related to that many logging processes?

Regards,


Pae
