Hi @momaer!

There is an easy solution to fix that. You need to set the environment variable USE_ZEND_ALLOC=0. (Source: http://stackoverflow.com/a/10092026/2560143) I had the same issue but starting my application this way worked for me:

USE_ZEND_ALLOC=0 php app.php

You can write a little startup script or define the variable maybe in your .bash_profile.
For usage in a script use:

export USE_ZEND_ALLOC=0

Kind regards

Resources are unsupported.

Anecdotally, you should try using stream_socket_* functions, as they appear to behave a little better.

If resources break, there is nothing I can do to fix it ... sorry ...
