Topic: (9)Bad file descriptor: mod_fcgid: can't truncate existing t

[javii]

Hi, I'm having some strange problems with Apache running PHP with mod_fcgid.

Most things works fine but when I try to use Wordpress Uploader, i get 500 errors:

[07/Nov/2011:17:02:27 +0100] "POST /wordpress/wp-admin/async-upload.php HTTP/1.1" 200 425 "-" "Shockwave Flash"

(9)Bad file descriptor: mod_fcgid: can't truncate existing temporary file

This is my fcgid.conf:
LoadModule fcgid_module modules/mod_fcgid.so

<IfModule mod_fcgid.c>

<IfModule !mod_fastcgi.c>
AddHandler fcgid-script fcg fcgi fpl
</IfModule>

FcgidIPCDir /var/run/mod_fcgid/sock
FcgidProcessTableFile /var/run/mod_fcgid/fcgid_shm

FcgidIdleTimeout 300
FcgidProcessLifeTime 1800
FcgidMaxProcesses 100
FcgidMaxProcessesPerClass 8
FcgidMinProcessesPerClass 0
FcgidConnectTimeout 120
FcgidIOTimeout 120
FcgidInitialEnv RAILS_ENV production
FcgidIdleScanInterval 10
FcgidMaxRequestsPerProcess 10000
FcgidMaxRequestLen 20971520
</IfModule>


Any help would be appreciated

Is there a file size from which on it doesn't work any more? Do smaller files work? Where is the php temp dir in your php.ini set to? How is the permission of that folder?

it would be nice if you could provide the error log from apache in that time when you upload a file and also if you have enabled the php error log.


Are you running some kinda linux / unix? from the paths it seems so

apache verion?
php version?
mod_fcgid version?

No, it is ramdom, when you upload 10 files, it usually uploads 2 or 3, it doesn't matter the size of each one. upload tmp dir in php is set to /tmp and that directory has 777 permissions.

This is what I see in logs:

PHP logging is enabled but nothing is logged by PHP.

OS: Centos 5.5

Thank you!!!

I don't see there any 500 error in that log part ou posted. O_o

Cause it works with a few files, but now with many I guess there is a time out error. But I'm not sure since I see there is a async-upload.php. So I think it uploads each file in a own upload process.

To what is your exection time set in php.ini? Did you tried with an increased time?
