large http upload freezes

[tszarans]

I have a working setup of jfileupload 2.6 . If I try and transfer a large file via http (200M+) the progress bar stops at around 77% and does not continue. I am using apache 2.2/mod_perl2, small files however work without any issues. Files that are 100M get uploaded no problem.

After waiting for a long period (5-10 minutes) and hit cancel I get the follow log message in the apache error log.

Apache2::RequestIO::read: (70014) End of file found at (eval 1972) line 5

The java console log does not show anything of note.

Anyone have any ideas?

Thanks!
Tony

It might be a timeout issue or file size issue on server side. Could you check your Apache/Perl configuration?

[tszarans]

I don't believe it is a timeout issue, as the upload happens very fast over the local network (1 to 2 seconds) 3/4 of the 100M is uploaded, then the pause happens (status bar stops).

I'm using a default install of Apache 2.2 on CentOS 5.4 - what would I look for regarding timeouts?

[support]

Time out usually occurs after 15 minutes so I thunk you're correct, it's not a time out issue. So, I think it's upload size issue with Perl or Apache. Could you check in your Apache or Perl configuration for HTTP POST size limit?

[tszarans]

I'm not 100% sure what to check for. Apache 2 documentation has options regarding LimitRequestBody (default 0 - means unlimited or 2G) which I do not have set.

The upload java client is freezing before handing off anything to the perl program.

This is the log from the java console on a large file:

This is the log from the java console with a small file:

This log reports that upload completed. Then it tries to forward to another page. Does it freeze after upload?

[tszarans]

No - the progress bar does not complete and the web server does not see the forward request.

Mmmhh, it does not match to logs. Which JRE version do you have?
