HI everybody~
I'm running apache-tomcat server on ubuntu 9.10.
As you can see below, last 2 numbers mean %I, %O.
%...I Bytes received, including request and headers, cannot be zero.
%...O Bytes sent, including headers, cannot be zero.

But sometimes, I can see that the %O is ZERO. there is no problem on apache thread or tomcat thread.
I'm appreciate If you can explain this.

thanks for reading.
