Hi,
Just for the record and the sake of the archive, I've tracked down the
problem using strace.
After filtering the NOENT character combination out of the strace log,
I've noticed, that 2 files were symlinks, but the symlinks were pointing
outside of the chroot.
The link targets were /etc/locale.alias and /etc/localtime
After linking them from the chroot, the problem seems to have disappeared.
I followup, if anything else comes up with this.
Thank you for your help,
Best regards,
Peter Balogh

Hi Frank,
I've just inserted the following line on the top of the apache2.conf
ChrootDir /hosting
I didn't do anything else, to make it work, and that's the only line
I've removed, to fix the issue
Best regards,

Hi Frank,
I can try a PHP list, but it's clearly an apache chroot related
problem.

Hi,
I've tried searching the archives (the FAQ is 404 at the moment),
but
couldn't find any tread regarding my issue.
I have an Ubuntu 11.04 server running 2.6.38-10-server
I've a stock apache2 and php5 installed from apt. Nothing fancy, no
extensions or patches.
I've chrooted the apache to a directory, and moved a few sites to
the
server.
The sites loads fine for the first few times, but after a few
reloads, I get a strange PHP error. From the logs:
[Tue Sep 06 00:41:57 2011] [error] [client 80.98.32.172] PHP
Warning:
Unknown: failed to open stream: No such file or directory in Unknown
on line 0
[Tue Sep 06 00:41:57 2011] [error] [client 80.98.32.172] PHP Fatal
error: Unknown: Failed opening required '/hosting/site1/index.php'
(include_path='.:/usr/share/php:/usr/share/pear') in Unknown on
line 0
Few minutes later, or after a restart, the sites are working OK
again.
If I disable the chroot, everything works fine.
Does anybody have a clue, what did I do wrong, or how can I figure
out the problem?
My only idea, is that I don't have a required so file in the chroot
path, when apache runs out of concurrent instances, but I have no
idea, how to figure out, what's missing.

Balogh,
How did you build your chroot? If you used apache httpd directives,
pastebin them in here. If you used your OS to chroot, you're falling
outside the scope of this list, definitely.

Balogh,
If you can reproduce the error reliably, you can strace the httpd -X
process, and find out exactly where it fails.
