#31080 [Ana]: ftp_connect() fails on a system where there is a large number of open files.

ID: 31080 User updated by: jon at destra dot com Reported By: jon at destra dot com Status: Analyzed Bug Type: FTP related Operating System: RedHat Linux Fedora Core 2 PHP Version: 4.3.8 New Comment: Sorry, I forgot you get to deal with folks that can't configure a server reporting things as bugs when they aren't. :) Previous Comments: ------------------------------------------------------------------------ [2004-12-15 03:57:22] sniper@php.net Why didn't you give that RH bug number in the first place? Would have saved our time a lot. :) ------------------------------------------------------------------------ [2004-12-15 02:30:21] jon at destra dot com Please note I opened this ticket at the suggestion of Wez Furlong. Please also take a look at the following: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=125258 ------------------------------------------------------------------------ [2004-12-15 02:19:57] jon at destra dot com 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. [root@ozhlin01 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." [root@ozhlin01 root]# cat /proc/sys/fs/file-nr 4575 0 32768 That gives a more relevant number I expect. Hope that helps some. ------------------------------------------------------------------------ [2004-12-15 01:28:41] sniper@php.net 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) ------------------------------------------------------------------------ [2004-12-15 00:55:04] jon at destra dot com Ahh, no I didn't. I have more then enough file descriptors but PHP is not using them. [root@ozhlin01 root]# cat /proc/sys/fs/file-max 32768 I suspect it is hard coding it's max number of file handles? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
