Redmine

Hi,

I'm having issues with large file uploads (over 10MB or so) not uploading and saving when running Redmine under LiteSpeed on CENTOS 7.8 virtuozzo. If I switch LiteSpeed off and use Apache instead it all works fine. I can't see any relevant file size or memory limits in the LiteSpeed configuration (mostly a stock setup); where there are limits set they are in the order of gigabytes (e.g. 2GB) which I hope would not affect the ~20MB files I'm currently failing to upload.

When attempting to upload the file as an attachment or to the "files" section of a project the progress bar counts up, the upload script returns a HTTP 200 and Redmine seems happy with the file, however when I save the issue I get an error message "1 file(s) could not be saved." and I can see the file has not appeared in the files directory.

Here is what gets logged during a successful upload (around 1.6MB):

Started POST "/uploads.js?attachment_id=1&filename=room.jpg&content_type=image%2Fjpeg" for 86.152.124.26 at 2020-08-13 16:52:45 +0100

Here is what gets logged during a failed upload (around 26.7MB):

Started POST "/uploads.js?attachment_id=1&filename=news.zip&content_type=application%2Fx-zip-compressed" for 86.152.124.26 at 2020-08-13 16:51:25 +0100
Processing by AttachmentsController#upload as JS

Completed 200 OK in 36ms (Views: 11.8ms | ActiveRecord: 12.3ms)

As you can see there is an important missing line in the log: no "Saving attachment". I don't "speak" Ruby, but edited app\model\attachment.rb with some additional logging and can see this:

• files_to_final_location is still run when the upload fails
• if @temp_file is false, so that code block never runs

Working backwards:

• file=(incoming_file) is still run when the upload fails
• unless incoming_file.nil? doesn't succeed, so that code block never runs

For some reason, it looks like incoming_file is invalid which means that @temp_file doesn't get assigned to and so files_to_final_location can't move the temp file to the files directory.

Unfortunately, I don't know enough Ruby to follow back further up the chain, which is why I've had to turn to this forum for guidance! Any help would be much appreciated.
