Summary: Impossible PHP Fatal errors produced when APC is
enabled
Status: Open
Type: Bug
Package: APC
Operating System: Centos 5.3
PHP Version: 5.3.2
Block user comment: N
Private report: N
New Comment:
I occasionally suffer from this same issue with APC 3.1.3p1 using PHP 5.3.8 on
RHEL 6.2. Apache version is 2.2.15.
I don't have a simpler test, and unfortunately I cannot always reproduce it. To
fix, I have to restart Apache. (More drastic approaches, such as deleting the
entire web directory containing the PHP files and replacing them with a fresh
copy without a restart, don't fix the issue.)
Apache, PHP, and APC support are all from RPMs, so there is nothing special
about my setup from that perspective. The disk hosting the files is local to
the
VM.

So the RYCrossSiteJSONService has a member variables like
the following:
protected $m_text_return_data = false;
protected $m_request;
protected $m_version = "";
protected $mUseDirectJsonFormat = true;
protected $mResult = null;
(with a couple more like $m_request that aren't set to
anything).
Also, there are two lines that Dathan left out that could
potentially have an impact (though I don't see how). The
code
inside run_service() is this:
$this->m_request = RYRequest::get_request();
global $global_context;
$global_context = $this->get_request(); // get_request just
returns $this->m_request
$container = $this->m_request->get_container(); // <-- This
is the line that produces the fatal error.
The RYRequest class has several class constants and a few
protected members, most of which are unset, and one that is
set
to a constant in the class.

I'm baffled, I cannot think of a good reason this would be a problem for APC.
is there a var $m_request = NULL; in the class definition of the second class?

Er... I meant that they are large files, where each one is 400
MB+.

Here are the backtraces when I collected the coredumps. How
should I get them to you? They're 400+M files...

I've been racking my head about how/why this would happen.
I'd love you to do a "gc" in gdb, which dumps a core for the memory. Break on
zend_error and dump a core, so that I can ask you to debug more things.
I cannot think of anything off the top of my head. But once you have a core, I
think we can really explore why this error happens.
I suspect I'm missing some magic OOP setting I need to do with 5.3.x. I've been
off apc for quite a while, doing other things ... so I might have missed a
change that sneaked in while I was away.
