Dear Friends:

Recently we received a submission file (PDF format) which is 1.8MB in size. The file could be successfully open on the local server with Acrobat or via OJS’ interface. However, when the editor accessed the file via the internet, the download process of this file was interrupted when it reached round 1 MB (50%). I wonder that is there limitation about the size of a submission file? Could anybody give me some suggestions? Thank you very much.

Best Regards,

Yaliang

Hi Yaliang,

No, there shouldn't be a limitation, and we've successfully used much larger files than that. Here are a few things to check:
  • Timeouts in PHP's php.ini configuration file. If a timeout is being reached, the server may break the connection.
  • Test with a different web browser on the client side.
  • Check to make sure that PHP's memory limit is not being reached. (I don't think this is likely to be the problem, but ensure that the memory_limit is set to 16MB or higher.)

A Solution for Microsoft's IIS.

Finally, I figured out and fixed the problem by assigning a smaller value to the property "MinFileBytesPerSec" for IIS. This property is used to configure the minimum throughput rate that HTTP.sys enforces when sending data from the client to the server, and back from the server to the client. The default value is 240 bytes per second, however, when there are problems with the internet traffic, the connection might be interrupted.
