I've tried strace -u www httpd -X
but the result is exactly the same as above.
As far as I know Apache needs to start as root to begin listening http ports and switches to www
user later for securinty reasons.
And yes, I'm starting it with -X option. And server seems to work except strace is not able to trace
anything...
