I have read somewhere that after PHP 5.4.4 the problem has been fixed for upload files >2GB (but did not see it in changelog). But I am still unable to upload via Chrome 3GB file.
Is anyone experiencing the same problem?
Debian 6, nginx 1.2.7.

2Why on earth someone would upload a 3TB file with a web browser? In my opinion you should find a better solution for it. – Ghigo Mar 08 '13 at 10:26

You might want to reconsider uploading this file in one go. You could have a look at plupload to utilize chunked uploads – hank Mar 08 '13 at 10:27

13TB? Even if we assume you had the storage space neccessary (unlikely IMO), How long would it upload? Even if we assume a good line (24 Mbps - which is a typical _download_, not _upload_ speed where I live), it would still take [11.5 days](http://www.wolframalpha.com/input/?i=3TB%2F24Mbps) to upload. – John Dvorak Mar 08 '13 at 10:29

1Do you really mean 3 TB or rather 3 GB? – Christoph Grimmer Mar 08 '13 at 10:34

... not to mention - you need to keep both parties _and_ the connection alive for the entire time. This alone is a challenging task. – John Dvorak Mar 08 '13 at 10:34

@ChristophGrimmer-Dietrich good note (it still takes 17 minutes over said line). – John Dvorak Mar 08 '13 at 10:36

this is a rediculous idea, do not upload files that big via HTTP :) – Andrew Mar 08 '13 at 10:47

3GB file via http is fine :) – Wiggler Jtag Mar 08 '13 at 10:48

Ok, some info after quickly checking around. In the documentation to post_max_size (which is apparently not in effect after PHP 4.2.3, see http://www.php.net/manual/en/ini.core.php#ini.post-max-size) it is told that memory_limit is also relevant for file uploads. If I get it right this means that PHP will store the full file in memory during the upload. This tells me that some chunking would be smart... If you don't have a lot of RAM available that is. If you have that much RAM available it seems you have to increase the memory_limit, too. Hope this helps a bit.

hmm I've got 8GB ram and memory_limit is set to 1024M and uploading 2GB file without chunking is not a problem. It can't reserve whole memory limit, cause several concurrent uploads would burn the server. – Wiggler Jtag Mar 08 '13 at 10:50

nginx client body size, upload file size limit, post size limit, everything is set fine. Following the bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=685383 it seems like just a part of php5.4+ is fixed, not all the parts... – Wiggler Jtag Mar 08 '13 at 10:52
