Sorry, I probably should have re-stated the problem:
We're using Python 2.3.5 on AIX 5.2, and get the follow error messages
from some of our code. I haven't yet tracked down exactly where it's
coming from:
sem_trywait: Permission denied
sem_wait: Permission denied
sem_post: Permission denied
We don't run these scripts as root, so I can't say whether they work as
root. I suspect they would, though, since root has permissions to do
anything.

I'm I would be very concerned about these. Permission denied is
somewhat baffling to me. man sem_wait on Linux doesn't show EPERM as a
possible error condition.
The code that likely generates these messages is in
Python/thread_pthread. h near line 319.
Do you have lots of threads? Do you make heavy use of semaphores?
Maybe they are running out or something. Do you know if your locking
is really working?

I'm not sure. I don't know what the Permission denied really means.
I wonder if there some weird compiler optimization thing going on. Not
that I'm blaming the compiler, it could well be a python problem. I
just don't know.
Do you have any memory debugging tools that you can run python under to
see if there's something weird python is doing? Valgrind should work
on PPC now, but you may need to apply a patch, I'm not sure PPC support
is mainline in v3. Other possibilities include purify if that works on
AIX or sentinel.

Hi,
I have just recently build python 2.3.3 on an AIX 5.2 version using gcc
v3.3.2 (i built python as root and installed gcc from a rpm file).
When we run any python script as root they work. But any other
user produces the following three messages;
sem_trywait: Permission denied
sem_wait: Permission denied
sem_post: Permission denied

Well, as the subject says....
Briefly, when I try to run *any* wizard, I get a simple dialog, stating

I suspect this is a windows (XP) problem rather than an actual Access
one, as the error only occurs in my power user (and any other) account.
It goes away if I am logged on (to windows)...
