Only environment where I (and others) have been able to reproduce this is PHP 5.6.7 on Ubuntu 14.04. I have tested on few CentOS servers with PHP 5.4, 5.5 and 5.6 and they all work fine. Also on a Debian server with PHP 5.4 the same script works fine. More info here: https://github.com/zendframework/ZendService_Apple_Apns/issues/19 Test script: --------------- Unfortunately I haven't been able to reproduce this without a valid SSL stream so the example code requires a connection to Apple APNS sandbox server and a valid local certificate provided by Apple (which I obviously cannot share). If anyone knows how this kind of connection could be established in a more generic and easily reproducible way, that would be great. https://gist.github.com/cvuorinen/1640b1a8ff2a7a19dd8e Expected result: ---------------- string(0) "" Actual result: -------------- Fatal error: Maximum execution time of 10 seconds exceeded in /tmp/stream_test.php on line 27 Call Stack: 0.0001 233600 1. {main}() /tmp/stream_test.php:0 0.4907 236528 2. fread() /tmp/stream_test.php:27 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69402&edit=1
