What kernel are you using?
Same problem here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=83364

Could you run "strace -o/tmp/trace /usr/sbin/httpd" and attach /tmp/trace?
Or don't bother - I've reproduced this, it happens when you boot the 2.4.18 kernel not the 2.4.20 kernel.

Problem appears to be that Apache (APR) detects the working sem_open() in glibc at build time (running on a .20 kernel), but sem_open() *only* appears to work in the .20 kernel.
Many thanks for the reports. This is fixed in httpd-2.0.40-20.

Just for the records: I do run a 2.4.20 kernel! But anyway, 2.0.40-20 fixes the problem for me.
This problem is unsolved with my 2.2.20 kernel and apache 2.0.45 ...
You may still run into this bug if you run a non-Red Hat-compiled httpd on a non-Red Hat-kernel - but neither of these things are supported.
I just wanted to mention that I ran into this problem when I built a 2.4.21 kernel using Apache 2.0.47 (also built from source). I made sure my /usr/include/linux was symlinked to /usr/src/linux/include/linux, rebuilt apache, and that fixed it for me.
