Question

Due to unknown reasons since a few days my Plesk server will no longer collaborate with PHP file uploads.

Testing was done with a 1.8 MB mp3 file and an even smaller movie file.

I tried to debug my way through this issue..

upload_max_filesize = 100M

post_max_size = 128M

open_basedir is either off or set to two directories, one of them being /tmp/

upload_tmp_dir = /tmp
memory_limit = 4096M (due to other reasons this is set extra high)

/tmp comes like this:

drwxrwxrwx   4 root root  200 Mar 29 14:09 tmp

Linux version 2.6.32-5-amd64 (Debian 2.6.32-35) ([e-mail]) (gcc version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Tue Jun 14 09:42:28 UTC 2011

My forms use multipart/form-data, so this is settled, although i also tested with two different ajax upload scripts – both of which usually work just fine.

I get no error messages whatsoever. All i know is that the tmp file is not there after uploading. And that’s that.

Does anyone know what is going on here?

Thank You!

As stated in your comments you have a overflow mounted on top of /tmp. This behaviour actually indicates, that /tmp is full, because if /tmp is full a script /etc/init.d/mountoverflowtmp will automatically create a RAM-disk that is 1mb in size. So I suggest to umount overflow and then to clean up your /tmp
