I should probably add that I've tried running this both as
root (su root; ulimit -n 5000) and using sudo (sudo php ...).
Same result.

I used ulimit -n to increase the number of allowed open
files, otherwise it wouldn't even allow me to create 3000
files.
Now ulimit -a gives me:
core file size (blocks, -c) 0
data seg size (kbytes, -d) 6144
file size (blocks, -f) unlimited
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 10240
pipe size (512 bytes, -p) 1
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) 100
virtual memory (kbytes, -v) unlimited
Can't find anything else which relates to file descriptors
and Mac OS X.

Looks like MacOSX has max number of file descriptors set to 1024 or
something like that.
I don't have MacOSX around here, but I guess this fact should be
documented somewhere @ apple.com.
Could you check it?

Have now done a bit more testing, and it only happens if you
try to open more than 1017 files and then try to open a url.
Have tried opening urls with fopen(), curl_* and exec
("wget"). Same end-result, they don't connect.
PHP doesn't generate any error messages when trying to open
using fopen(). When trying it with the curl functions, curl
returns with "couldn't connect" but if you turn on more
debugging it comes back with "Unknown error: 0". When trying
to exec() wget it stops as soon as it gets a connection and
is about to output "200 OK"
(i have read the how to report bugs, but can't find what i'm
missing to include)

Description:
------------
When opening a lot (3000 in this case) files under Mac OS X,
network connectivity disappears.
This has been tested under Linux 2.6, and works fine.
Reproduce code:
---------------
$fp = array();
for($x=0;$x<3000;$x++) {
$fp[$x] = fopen("/tmp/$x", "w");
}
$url_fp = fopen("http://www.google.com";, "r");
var_dump(fread($url_fp, 1500));
Expected result:
----------------
To get the first 1500 bytes from www.google.com
Actual result:
--------------
string(0) ""
