#39883 [Opn->Fbk]: ftp_get - coredump

ID: 39883 Updated by: tony2001@php.net Reported By: youza at post dot cz -Status: Open +Status: Feedback Bug Type: FTP related Operating System: Fedora Core 4 PHP Version: 4.4.4 New Comment: I don't get it either. If there is no way to reproduce it NOT on your server, then I'd suspect that the problem is somewhere else on your server and not in PHP. Previous Comments: ------------------------------------------------------------------------ [2007-01-08 10:26:55] youza at post dot cz No, the PHP CLI command is ok and file is transferred. I use the ftp_nb_get - this function ok (no problem). What's the difference between ftp_get and ftp_nb_get in the source code ? Hmm, our server is very mass hosting system - the number of virtual servers is cca 1800 (not all very active). The config contains : ( example for one virtual) <VirtualHost 111.111.111.111> DocumentRoot /path/to/home/ ServerName www.xxxxxxx.xx TransferLog /var/log/httpd/XXX/home/access php_admin_value include_path .:/path/to/home/ php_admin_value doc_root /path/to/home/ php_admin_value open_basedir /path/to/home/ </VirtualHost> i reduce the number of virtulas to 950 and ftp_get work ok ( 20 times test). The next tests is very interesting !!!! 1. Virtual hosts 1205 - error ( segmentation fault) 2. Virtual hosts 1204 - different error - www page in the Firefox show error and the same error messages were saved to file name "0" - zero !!! FTP file not transferred. -rw-rw-r-- 1 apache webuser 445 Jan 8 10:06 0 The "0" file contains: [08-Jan-2007 10:00:17] PHP Warning: ftp_login() expects parameter 1 to be resource, boolean given in /path/to/home/test.php on line 37 [08-Jan-2007 10:00:17] PHP Warning: ftp_get() expects parameter 1 to be resource, boolean given in /path/to/home/test.php on line 43 [08-Jan-2007 10:00:17] PHP Warning: ftp_close() expects parameter 1 to be resource, boolean given in /path/to/home/test.php on line 51 3.

I don't get it . ------------------------------------------------------------------------ [2007-01-03 15:30:30] tony2001@php.net Are you able to replicate it using PHP CLI? Or is it reproducible only with Apache2? For the record, I don't see any problems with fetching the "welcome.msg" from the server you mentioned using the reproduce code of yours with _both_ Apache2/worker and PHP CLI. ------------------------------------------------------------------------ [2007-01-03 15:10:16] youza at post dot cz Yes I reproduce it in the public FTP server: URL: ftp://atrey.karlin.mff.cuni.cz/welcome.msg Result: Warning: ftp_get(): Opening BINARY mode data connection for welcome.msg (241 bytes). in /web/docs/tester/youza/ftp/test.php on line 43 apache error.log: child pid 24559 exit signal Segmentation fault (11) The file not copied but create empty: -rw-rw-r-- 1 apache webuser 0 Jan 3 16:04 test_l.dat ------------------------------------------------------------------------ [2006-12-30 01:00:01] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.
