Also, I run constantly a lot more complex PHP-scripts on both FC2 and
FC3 servers, on different kernels and by using normal socket and stream
functions. They all function perfectly well. All this seems to point to
the new stream_socket functions as stream_select works with all the
other streams except the ones opened with stream_socket functions.

Only change has been the service port and sometimes the IP if the
actual server doesn't host it's own SMTP. I've tested the SMTP
availability with telnet and by using fgets instead of stream_select.
So yes, the test code fails on FC3 and works on FC2 when the actual
ip:port is changed to point to an available SMTP service.

Have you pasted the script that you're actually running with those
straces?
Are you really using the one from your initial post?

Also, all the kernels I've used are different versions of FC3 stock
kernels without modifications. As FC3 is quite popular Linux I'd assume
that many people will have problems with the new functions when they
adopt them. Of course it can be a kernel problem, but it can also be a
PHP problem which only exhibits on FC3 or with certain kernel settings,
but that's more your field to conclude than mine :)

Yes it works with FC2 but not with FC3, but I have tested it with
several kernels the only thing that matches is Fedora Core version.
Also socket_select and stream_select works perfectly well with other
streams/sockets, only exceptions are streams returned by
stream_socket_client() or stream_socket_server().

So, PHP works fine on FC2, and the same version of PHP doesn't work on
FC3?
Sounds like you have a problem with your kernel; if so, this isn't a
php bug.
