PHP has encountered an Access Violation at 77FCAFF8

Question

I am running a PHP site that uses Ajax and jQuery as well. The site will run fine for quite some time, and suddently my pages (and ajax-retrieved sub-pages) comes back with the message

PHP has encountered an Access Violation at 77FCAFF8

It seems that rebooting the server corrects the issue. Running PHP Version 5.1.6 (Windows NT 5.0 build 2195). I did a some searching on here and some other sites, and there seems to be no fix..

URL REMOVED

UPDATE: I think I'm on to something.. will get back to you.

UPDATE After reviewing the IIS setup, i noticed there was no Handler Mapping setup for the website. This, of course begs the question - how did it ever work in the first place, when it was originally setup this way!? I added the handler mapping and it seems to be Okay so far.

UPDATE The problem popped its heads out again this morning after 36 hours without encounering it. Back to the drawing board.

UPDATE We ended up just moving the site to a secondary web server where we were able to upgrade PHP without an issue.

Answer 1

This is a PHP issue somewhere. You could spend some time narrowing down which function you're using that is causing the problem. I would instead upgrade to a newer version of PHP. If still no luck, try a slightly older version. There have been significant changes with version 5.3.2.

Answer 2

After some research I think this may be the solution (Taken from http://bugs.php.net/bug.php?id=28929 ):

I realize this issue is AGES old, but it still manages to be the top hit on Google searches as of now (6/2010).

I fixed my own instance of seeing this error. W2k3, IIS6, PHP 5.2.6, MySQL 5.1.

The problem is in the pathing. When I used the MSI installer for MySQL without doing an "advanced" installation (where I could manage the install details), it added a path to the system environment that contained spaces. Even after changing the path environment to use the Windows short-name location of the mysql bin directory, it still didn't work.

The solution was for me to reinstall mysql and set the default installation path to just off the root (e.g. C:\mysql). Once I did that the error went away and my app started working.

There are a number of sites with a variety of potential solutions to this issue and several of them mentioned paths and the "libmysql.dll" file (in the "bin" directory of your mysql installation).

If this helps you solve your problem, consider leaving a comment here so others can see that it works.
