Server issue Attachment upload freezing at 100% using the Flash uploader

[Paul B]

Using the Flash uploader results in uploads freezing at 100%.

I tried with various file types; png, txt, jpg and it's the same for all.

The normal uploader works fine.

I have the same problem

I tried with Firefox 3.6.10 and the lastest version of chrome (for mac)

Strange... I have a screenshot that I can't upload, others work just fine.

I think it's because of the size?! The one in question is 270 kb large, the one that works is only 123 kb large.

Same problem...



As you can see, layout is also changed at 100%.

Additional info:
File: .jpg , 258KB

Browser: Safari 5.0.2
OS: OS X 10.6.4

It happened for me too, but I talked with my host because I know they have mode_security on, and when they turned it off, the problem was fixed.

Solved it indeed.

For others: create a .htaccess file in the root of your domain with the following content:

SecFilterEngine Off

@devs: right before the upload bar reaches 100%, the layout still looks bad (like in the screenshot of post #4).

Many thanks Omri.L, that solved the problem

Mike still wants to do some more debugging on this issue so he wants to leave it here for now.

Finding out what caused this would be awesome, mod_security is a good idea.

Many thanks Omri.L

You're very welcome

I've seen a couple different references, but it looks like Flash may not send the multipart boundaries correctly.

The second page has an interesting workaround at the very end (the SetEnvIfNoCase line). Anyone with the issue care to try that? (Note that the "ot buffer..." part should be part of the previous line.)

 

[dutchbb]

I have this problem again now, even with SecFilterEngine Off

Also seeing this problem. Some users report it sticks at 100%, others that it doesn't move from 0%.

**** FIXED *****

I recently moved hosting companies from one VPS to Linode. After the move everything was working fine, but I started having members complaining that some images were not uploading properly.

They would upload an attachment (image) and the progress bar would hit 100% and then nothing would happen.

After a bunch of researching, I changed the following settings for PHP and MySQL to match my previous VPS. I'm unfortunately not sure which one was successful in fixing the problem, but wanted to post here (and a few other related threads) to share that this worked for me!

pico /usr/local/lib/php.ini
memory_limit = from 32M to 158M


pico /etc/my.cnf
max_allowed_packet=268435456 to max_allowed_packet=64M
wait_timeout=10 to 45

(make sure to restart your services after you make the changes)
