Running PHP 5.4.15 / ZF 1.12.3 (upgraded from 5.4.12 or 13 I believe). Running nginx w/ php-fpm, also tested with Apache. NOTE: This appears to be related to APC. I would highly prefer APC, and cannot use eAccelerator because of issues w/ Doctrine and DOCTYPE Entity declarations.

When validating the form, it is causing a signal 11 sigsegv across the board (different versions).

Running the form validate inside of the HTML template (shouldn't be a problem)

$p = Zend_Controller_Front::getInstance()->getRequest()->getParams();
if (!$form->isValid($p)) { .. }

I dumped out what I could from the backtrace.

Any experience/insight with this or related issues would be helpful!

Thanks!

  • The dump seems to belong to shutdown sequence with several destructors. I am not an expert, but there may be an unhandled fatal error or exception causing this. – Volkan May 21 '13 at 06:54
  • which version of APC are you using? Have a look at http://stackoverflow.com/questions/9611676/is-apc-compatible-with-php-5-4-or-php-5-5 for explanation on what's going on. From personal experience, the latest beta of APC is far more stable than previous versions – periklis May 21 '13 at 07:41
  • periklis, thanks for linking. I tried multiple versions of APC, to no avail. I've stuck on the 5.4 PHP branch (upgraded a few minor versions) but same result. When I ran an strace, it did seem to crash right before sending the X-Powered-By header, so I was leaning towards some sort of cleanup/memory issue. I'll wait for a newer APC and give it a go, otherwise maybe throw 5.5 on here as a test. Can't hurt... – Austin May 21 '13 at 18:23
