PHP has encountered an access violation...

[Martin]

I have an intranet-only site running in Windows XPPro, IIS 5.1, PHP
5.2.5. I have not used or changed this site for several months - the
last time I worked with it, all was well.

When I tried it just now, I am getting the subject error message
(specifically: PHP has encountered an access violation at 00F76E21).

The error is NOT occurring on every page request (but it is on most of
them) and, when I get the error, simply pressing <F5to refresh the
page results in the page being served successfully.

Some googling around indicates that "permission s" are not set
correctly. But, if that was actually the case, a <refreshwouldn' t
work either would it? This seems to be a sporadic issue.

Any ideas as to what's going on here?

Martin,

There are several bug reports at bugs.php.net similar to what you are
reporting. But not knowing what your code is doing, I have no idea what
might be related.

You could look through them and see what you can find. Upgrading to
5.2.6 may also fix this bug.

And if you don't find anything, I would recommend you put together a
small test case showing the problem and report it as a bug.

Most of the bug reports I've seen on this suggest it's an issue with
running PHP and an ISAPI filter.

Perhaps you could try setting it up as CGI. I vaguely remember running
into a similar issue the one time I attempted to run PHP under Windows.
Though I believe I solved (side stepped) the issue by running Apache
instead of IIS, which my not be a solution for you.

Hi,

First, to find the reason for an access violation, you must use
debuggertools for IIS.
You can find better help in this newsgroup:
microsoft.publi c.inetserver.ii s (also with finding the right tools
to create a bugreport.)
I heard PHP5.1.somethin g had some issues when trying to free the
same amount of memory twice. (Not sure if that is related)

And I have a, possibly lame, suggestion: Switch to Apache (1.3 or
2).
Most techies consider IIS an inferior webserver.

Regards,
Erwin Moller

FWIW:
I have been struggling to solve a similar problem under Apache. :(

Still dont know the exact cause, but somehow a mySQL dll was the wrong
version.
Replcing it with another 'fixed' it.
How the wrong dll was referenced I still dont know.

Some kind of internal bug in PHP. The access violation error tells
NOTHING and you don't need to waste time on it.

Try different PHP versions or use apache to host PHP scripts. Apache
is less problemic with PHP in my experience.

hmmm...it tells you the application is trying to do something that it is not
allowed to do. your comments seem to be the only thing wasting anyone's
time.

well, well, well. seems like you don't really think it is 'some kind of
internal bug in PHP' after all! now you're saying it's IIS, or any other
webserver but apache.

if you don't have enough information to go on, don't assume so wonderfully
and precisely what the specific problem is or what is going to solve it!

Off course there are many kinds of access violations, but this seems to
me like PHP is trying to read from a memory address it does not has
access to. This is most likely a bug in PHP (or some other software) or
broken hardware.

Try testing your memory (maybe with memtest86) and up-/
downgrading your PHP.

At your suggestion, I downloaded memtest86 and ran it but it reported
no memory problems - everything was ok.

Am continuing to try to diagnose the problem.

Jerry - Thanks for the suggestions.

I'll upgrade to 5.2.6 but, maybe you could answer a question for me?
How does one "upgrade"? Do I have to do a complete install of 5.2.6?
Or is it possible to simply update certain components some way?

I looked around the PHP site but couldn't find anything that explained
this. Is there a site somewhere that explains a little more fully how
to do this?

Thanks.

The problem is probably not specifically with PHP, more likely with
the ISAPI DLL or IIS. The access violation does, indeed, tell you
something.

Try different PHP versions or use apache to host PHP scripts. Apache
is less problemic with PHP in my experience.

The OP shouldn't have to switch server environments, as PHP can run
just fine on IIS, when configured properly.

You need to do a complete install. There isn't an upgrade path.

But it's pretty painless. If you previously used the zip/gzip files,
just move your old files to another directory (for backup) and unzip the
new files in the same place. Ensure you keep your current php.ini file.

If you used an installer, you should again backup the files (just in
case), remove the old and install the new in the same place.

Because the access violation is not caught and correctly reported in
PHP module, i.e. the php module crashed.

Therefore it's an internal bug.

Yes it is. Unless you want to spend time debugging IIS & PHP module.

The OP was trying to find out what the problem is. It doesn't help
him.

Even if he finds out why the problem access violation was casued, he
cannot solve it by fixing php or iis. So why waste time on things you
cannot fix?
