[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(i think)
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
