The problem is that in Apache we create the semaphore as root, and then
try to use it as a child process running as nobody. Of course, the
child process doesn't have the rights to access that semaphore. The
attached patch solves the problem for HP/UX, but how is this working
anywhere?
As a side note, this is actually a bug that has been waiting to bite us
for a while. Permissions in APR have never been abstracted correctly.
For the next version of APR, somebody will need to really put some
effort into abstracting permissions. I am more than happy to help, and
I have some thoughts on how to do this, but it will be VERY hard to do
correctly.
