New Comment:
There is no nfile limit in apache server.
When i change nfile limit I have the same results (error or seqfault)
Limit are set to unlimited/high value intentionally for this test:
This is results in
system('ulimit -a');
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 1048576
pipe size (512 bytes, -p) 8
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) unlimited
virtual memory (kbytes, -v) 250000
I would like to emphasize that when I use php 5.2 everything works fine
within the same limits/apache2 config.
The problem is connected with php 4.4.7 in mod_php.
When i use 4.4.7 in cgi, or php 5.2 in mod_php (same ulimit and apache2
config) or 5.2 in cgi mode script return good results.

You've run into your system's file descriptor limit.
Not PHP problem.

Well, as this bug is version 4.4.7 related, I hope that this is some
kind of automatic reply :D
Downloading 5.2 will solve the problem, but it would be nice to see it
corrected in php4.

Description:
------------
I found problem in fsockopen() when I use php as module mod_php in
apache2.
When I create many vhost fsckopen() doesn't work good and generate
child sigterm error.
I made some experimets with vhost number:
vhosts number - error
less than 1005 - work fine
1006-1007 - white page (no error)
1008 - around 1164 - "Operation now in progress (115)"
around 1150 - around 1164 - "Bad file descriptor (9)"
around 1164 - around 1200 - "Operation now in progress (115)"
1200 and more - apache child sigterm
core in sigterm:
(gdb) bt
#0 php_hostconnect (host=Cannot access memory at address 0xc
) at /srv/dev-dev/php4-debug/php4/php4-4.4.7/main/network.c:490
Cannot access memory at address 0x4
(gdb)
When I use php in cgi/cli mode all works fine.
Reproduce code:
---------------
<?php
$fp = fsockopen("www.onet.pl", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: www.onet.pl\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>
