Out of memory

[efeferrari]

Hello @Edujugon,

I getting Out Of Memory error sending push to iOS.

I tried with develop and production url of Apple, but is always same error.

PHP v5.6.30
edujugon/push-notification: v2.2.0

Hi @efeferrari
Have you tried to test it in other environment?

[efeferrari]

I tried in local and development environments. In both, I set ini_set memory_limit to 1 GB.

Same issue, Any luck on finding a fix for this?

[efeferrari]

I try with a new iOS certificate and works fine, but it's still a bug get an "Out of memory" instead an "invalid certificate" 🤔

[Edujugon]

Hi @efeferrari @Drozes ,
I'm really busy these days and I'm not able to check out this issue.

For now, as @efeferrari said , you can generate a new certificate and try with it. It's not the first time that generating a new certificate solves some issues..

Hi also having this issue with a new cert, anyone find the issue?

[Edujugon]

Hi @gl3nda85 ,

Could you try to call apnsFeedback() method and see if it returns any token?
Notice that method returns a list of tokes that should be removed from the deviceToken list to send the notification.
Then, try again to send the notification.

Let me know if that helped

Hi Edujugon,
I am experiencing kind of the same error: when trying to send pushes to APN the php starts consume memory, freezes and at the end I got "PHP Fatal error: Allowed memory....".
The feedback() method is not even called because all freezes on send().

Any clue?

Best,
Daniel

Laravel 5.2, PHP 7.0

Hi @danielz0 ,

In the next days I'll dig deeply into this issue. Would you share your certificate with me so I could do tests with that one as well? if so, send me a mail to edujugon@gmail.com

In the meantime, have you tried to generate a new Certificate? most probably is Apple who is refusing the connection to its server..

[danielz0]

Hi again,
I am sorry to say, but the same certificate used on another server works totally fine.
I have traced this for errors and I am sure that
class Apn extends PushService implements PushServiceInterface
public function send(array $deviceTokens,array $message)
is the one which generates problem.

In details I have two servers with Laravel 5.2 and PHP7.0
Both were working fine, until one day one of it stopped sending iOS pushes.

After days of tracing the only thing I got is
Symfony\Component\Debug\Exception\FatalErrorException: Allowed memory size of 536870912 bytes exhausted (tried to allocate 20480 bytes) in /default/vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/HandleExceptions.php:59

I have tried all tricks, from modules update to increasing memory limits - no luck so far.
When using strace I can see that the Apple push service returns 'operation in progress' all the time which increasing occupied memory and finally leads to memory exception.

Not sure, but personally I think it might be something connected with system libraries.

I am going to generate list of files your process is trying to open on both servers and compare.

Any suggestions are welcome.

Thanks!
Daniel

Maybe this will help you?

Hi @Edujugon
I think I found the problem which might be here reactphp/stream#64
Let me know your thoughts.

Best,
Daniel

[Edujugon]

Hi @danielz0 ,
Thank you for your support, I really appreciate it :)

Have you tested it in PHP 7.1.4 or 7.0.18 ? Does that work for you?

It seems to have a work-around for PHP < 7.1.4 (and PHP < 7.0.18) but since it has a performance penalty it may be the reason of that issue.

I have to test it in different PHP versions with a big data/payload to send.

[danielz0]

Hi @Edujugon,
Didn't have time to test this in php7.1.4 nor in 7.0.18, but will do it next week, as I plan to update at least one of my servers. For now I am using self-written script which chunks data into smaller sets.

The payload which crashed in my case contains 1000tokens and one-two lines in the message body.

Best,
Daniel

The new releases (3.x & 2.2.x) prevent of this error.
I'm closing this issue. feel free to open it again if the error persists.
