This means that your fastcgi ended unexpectedly. Check php-fpm(or whatever other handler you are using) logs. It's possible that you have core dump. Then try to use this to generace backtrace:

This means segfault, read what i wrote above. Provide backtrace from gdb.

stamster · 2016-08-23T10:11:08Z

With Phalcon 2.0.x and PHP 5.x this issue was also present, but only during high load.

Jurigag · 2016-08-23T10:12:48Z

Guys, please post backtrace, we don't anything how to reproduce this issue, you just posted some code of controller, i have controller and action too and it works for me.

I NEVER had such an issue on php 5.x and phalcon 2.0.x, php5-fpm uptime is like xxx hours.

Jurigag · 2016-08-23T10:39:18Z

Disable xdebug and post backtrace again. Also post whole backtrace, from beginning to end, this is beginning from #24 jump/function execute.

Also reading symbols etc is not needed, only backtrace of functions executed.

kcloze · 2016-08-23T10:42:09Z

Disable xdebug ,it's ok now.
Thanks.

stamster · 2016-08-23T10:46:22Z

xdebug - a tool which can cause many issues, and not only with Phalcon!

kcloze · 2016-08-23T10:49:31Z

We find it maybe same error code in view script.

virgofx · 2016-08-23T21:47:06Z

@Jurigag Can you help provide any more insight as I think this issue seems to be persistent with Xdebug + PHP7-phalcon -- definitely an issue in my opinion (currently disabled in my testing)

stamster · 2016-08-23T21:55:46Z

IMHO, xdebug shoudn't be used at all with Phalcon since it interferes with PHP internals.

For instance, ionCube loader and Xdebug cannot work together officially for the same reason.

Jurigag · 2016-08-23T22:15:50Z

@virgofx what yu mean ? Just don't use phalcon and xdebug, don't see any other soultion to be honest, and there can be way too much things causing this.

virgofx · 2016-08-24T13:02:56Z

@stamster - I guess I'm curious as to why? Phalcon worked fine with PHP56 and XDebug. Debugging is very useful in enterprise and large applications. Why don't we just get a few more stack traces and see if @andresgutierrez can look into it?

Jurigag · 2016-08-24T14:57:27Z

Then post whole script to reproduce, best repository, whole stacktrace with both php and phalcon compiled as debug and then someone can look into this.
