Many thanks for the information Mike.
I think this is not a browser related issue, the same browser from the
same computer success on uploading a 19GB file before updating the server.
One of the updates is changing something that I am unable to determine.
Anyway, I'm using Firefox 38.0.1 on a Windows 7 Enterprise x64, if I use
Internet Explorer 11 x64 the transfer start on browser side but no
incoming file reach the server.
It is quite annoying, I was hoping any of you had faced this problem
before...

Hello all,
Sorry for interrupt you in the middle of new beta development but I have
found an issue on existing 4.11 ZendTo Ubuntu based that you could be
aware of.
I have downloaded the OVA (ZendTo-Ubuntu-x64-4.11-6.ova) and deployed it
making the minimal changes for being able to login and make a test. The
tool works properly for any kind of transfer without any issue or problem.
Then I make an update of the system, configured LDAP authentication and
increased the values of 'maxBytesForDropoff' and 'maxBytesForFile' to
20GB (21474836470) and after this, ZendTo is unable to make transfer
superiors to 2GB, when you start this kind of transfers the incoming file
rise in /var/zendto/incoming/ until it reach the 2GB limit, then it was
deleted and the browser keeps trying to send it without returning any
error.
In php.ini (/etc/php5/apache2/php.ini), after updating the system, both
post_max_size and upload_max_filesize are set to 50GB.
Are you aware about this "issue", do you know how can i resolve it?.
Many thanks in advance.
Marcos.

Hi, Marcos -
Which web browser and version are you using to upload the file(s) to
ZendTo? There were (and I guess still are) issues with different browsers,
different versions of browsers, and even the same version but on different
platforms that make their ability to upload files over certain size
thresholds an interesting challenge:
- all handle uploads up to 2GB OK
- many handle uploads between 2GB and 4GB OK but not over 4GB
- some handle uploads over 4GB OK
You might recognise those numbers as Magic Numbers of the Universe:
- 2GB = maximum value of a signed 32 bit integer
- 4GB = maximum value of an unsigned 32 bit integer
- >4GB = needs a 64 bit integer
Web browsers with problems can fail in different ways, such as:
- failing quickly
- appearing to hang and never complete the upload
- navigating/trying to navigate away from the upload page
It's probably changed since I did my tests way back when we started using
ZendTo but at that time we found no Windows browsers that worked with
files
over 4GB, one or two on a Mac that did work, and I think one on Ubuntu
that
worked.
So your next step is to test your setup using different browsers ? eg,
Internet Explorer, Firefox, Chrome, Safari, Opera, etc. Where you have a
choice, make sure you're running the 64-bit version of the browser (which
will likely require a 64-bit version of your OS as well?)
Cheers,
Mike B-)
