Sorry, I forgot you get to deal with folks that can't configure a
server reporting things as bugs when they aren't. :)

Why didn't you give that RH bug number in the first place? Would have
saved our time a lot. :)

It triggers the die. There is no more error information to report.
There is nothing in the ftp servers logs to help and I can't really
turn on verbose logging for it in a production environment.
This works fine on an indentically configured server with less open
files, or in light of the following I should say open file descriptors,
on it.
[EMAIL PROTECTED] root]# lsof | wc -l
89854
Which doesn't seem right...
"lsof lists all open files, including files which are not using file
descriptors - such as current working directories, memory mapped
library files, and executable text files."
[EMAIL PROTECTED] root]# cat /proc/sys/fs/file-nr
45750 32768
That gives a more relevant number I expect.
Hope that helps some.

What is the error it gives? (set error_reporting = E_ALL!)
Does the FTP server log have any clues why the connection fails?
At what point of the connection does it fail?
Put shortly: We need a lot more information!!
And how many files you HAVE open at the time of the failure?? ("lsof |
wc -l" command helps with that)

Ahh, no I didn't. I have more then enough file descriptors but PHP is
not using them.
[EMAIL PROTECTED] root]# cat /proc/sys/fs/file-max
32768
I suspect it is hard coding it's max number of file handles?

You just run out of filedescriptors. This is not something PHP can fix
for you. You either need to cut down in the number of Open files, or
adjust your kernel parameters.

Description:
ftp_connect fails on a server with a large number of open files.
Eg. In a virtual hosting environment where Apache has 1000+ log files
open.
Reproduce code:
---
$ftp1 = ftp_connect('127.0.0.1') or die("Couldn't connect to server");
Expected result:
Established connection with a handle via $ftp1.
Actual result:
--
The connection fails.
