Hi there,
We're experiencing the same problem here at Netlog. Also on production servers
when we have some load. Unable to isolate this issue yet. We're running php
5.3.5
and apc 3.1.9. If we disable APC the problem goes away.
Any clues here?

Updated to APC 3.1.5 and the problem still persists.

I'm seeing this error quite often on our production servers.
The problem seems to have something to do with APC cache, and after updating
the files or apc_clear_cache() some random anonymous function call breaks at
somewhere on our code.
I can reproduce the error on our production server almost every time, but I
have not yet been able to build a reproducible test case. It seems to be a
concurrency issue, so the reproduction most probably
requires concurrent APC cache clearing and lambda function calls.
We're running PHP 5.3.3 with APC 3.1.4 on RHEL. I could try to upgrade to APC
3.1.5 next.
Any help would be appreciated.

The code in which the problem occurred looks like:
<?php
$methods = array(
'pfd_hor_pap' => function (&$v)
{
if (!empty($v)) {
$v /= 13.66;
}
return true;
},
// ...some other lambda functions
);
// ...code that uses the array with lambda functions
?>
The error occurs at the definition of the first lambda function in the array.
The problem is that the error isn't reproducable (at least not when I want it
to be). That's why I'd like to know what the typical situation is in which this
error could occur.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
Please also ensure that you're having no Zend extension or opcode cache or
similar loaded.
