send multiples push give me some errors

[emimarz]

ok, I will try to explain this bug
I get the sample push to many and change it with my data
so, I send 1000 push to one device
then I found this
Tue, 13 Oct 2015 16:53:52 +0200 ApnsPHP[27994]: STATUS: Sending message ID 608 custom identifier: unset: 66 bytes.

remember, all push are sending to the same device so is a valid device id
I don't understand why push 600 can't be sent
if I change setWriteInterval to 0 more errors appear but all was sent also number 600
if I increment setWriteInterval always give me that error

Could you help me with this bug?
thanks in advance

I also experienced this issue while using another PHP APNS library (wrapper to a C library actually) https://github.com/adobkin/php-apn
I was trying to send a notification a 1000 times to the same recipient and it stopped exactly the same way at the 600th (status code 8 "invalid token" too)
My guess is that this is a restriction on the Apple side itself then.
I just saw this now as well http://stackoverflow.com/questions/34216006/apns-valid-token-receives-error-message.
