Yes, absolutely. That's the first thing I've checked. It is the file on server.

I tried it with no luck. I'm far from being a debugger expert, but what's happening doesn't look
normal to me. strace starts fine and writes tons of stuff when the server starts. I wait until it's
done and make a request to that web page. Page is displayed but nothing is written in the trace log
at all, it sits where it stopped after the server start. I've tried -f option on strace but it's no
different. Also tried truss instead of strace - same story.
Last lines of the strace log are:
====- 8< -===================================================
open("/var/run/accept.lock.41858", O_WRONLY) = 12
geteuid(0x1) = 0
setgid(0x50
====- 8< -===================================================
(yes, last line is incomplete)
I've also tried strace-ing httpd itself, no difference. It does serve pages, it doesn't show
anything. I suspect this might be due to httpd falling down to user and group "www" (last lines hint
to that) and it can't be traced thereafter. But Apache doesn't start under root. Do I have any other
options here?
Are you sure you are passing the "-X", which puts it in single-process mode? You can try starting under a non-root user to see if the setgid is really the problem.
