Attachment upload fails with "HTTP error."

Daniel Urstöger

Hello there,

I wonder if somebody can help with my problem. Attachment uploads do generally work,
but I got a rather big PDF here. It is roughly 95MB in size. Upload of smaller files up to 20MB work,
but the 95MB file fails all the time with "HTTP error." for some reason.

We run Confluence behind a Apache proxy to have SSL encryption. After looking around and googling I checked the Apache error log and a few other things but couldn t find the problem. Maybe somebody got a clue for me?

Thanks!

We run Confluence 4.3.5 by the way.

Kind regards,
Daniel

Hi Daniel,

You might want to check the LimitRequestBody directory in your apache conf.

More information available at http://httpd.apache.org/docs/current/mod/core.html#limitrequestbody

Hey Daniel,

Another clue would be to check the attachment size settings: https://confluence.atlassian.com/display/DOC/Configuring+Attachment+Size

Regards,

Peter

Daniel Urstöger

Thanks Peter, but sadly I already set that to over 500MB.

Could you describe the error message in detail? Do you use any web proxy in between? Do you see any related messages in <CONFLUENCE-HOME>/logs/atlassian-confluence.log? Are you sure it is the size of the file, not the file name for example?

Daniel Urstöger

Well, that is the full error message I see in my browser. It comes up within the upload window, after the whole file has been uploaded (judging by the progress bar of Google Chrome). I will attach the log file soonish, I am currently not in the office

About the Proxy, well Apache gets the Requests and forward them to Confluence, this is for the SSL setup, as desribed in the Atlassian Wiki. I can also upload attachments with smaller size without any issue. And I also tried to upload a file smaller with the same name and that worked.

Hi Bhushan,

I checked but also seems like that isn t the problem.

how is Attachment Storage configured?

if it's set to Database you may adjust "max_upload_size" in your Database config file (i.e. my.cnf)

try after adding max_upload_size

Daniel Urstöger

Good point, totally forgot to mention that! I use MySQL als storage backend, and I set the max_packet_size to 1GB. So I guess that is also not it.

Daniel Urstöger

max_upload_size in the MySQL config?
