Network is unreachable: connect to listener
Is it normal to have the error message "Network is unreachable: connect
to listener" appearing every 1 second?
This appears after I used ab -n 10000 -c 100 ...

What kind of operating system do you use? I had a similiar problem in FreeBSD 4.5 and Apache 2.0.36 - 2.0.39. Solved it by setting the Listen-directive to 127.0.0.1

Did you exceed your maxclients during your test? Do you have a
Listen directive pointing to something other than the default
or an appropriately configured and working interface?
