Confluence 2GB Maximum File Attachment Size Limit?

I am trying to upload a 3GB video to Confluence. I changed the "General Configuration" settings to allow for up to 5GB files, and I've also checked the user's filestore on the server to ensure there is plenty of space for this file. However, when I try to upload the file, it gives me an error that the file is too large (larger than 2,048 MB). Is there a way to get rid of this limit? THANKS!

Kind Regards,

Hey Eddie, this is indeed a bug in Confluence. There seem to be a hardcoded max size limit, which is 2GB. You might want to watch this bug report - for any further updates.

Sorry for the inconvenience!

Hi Eddie,

In order to understand the cause of your issue we would need to review your atlassian-confluence.log to get the detailed stack trace.

However, since you have ensure that "General configuration" setting is on 5GB, could you please double check your attachment storage setting?

  • If its configured to be stored at file system, double check if there are still free space left for the attachment
  • If its configured on your database, double check if there are any size limitation configured on your database level. If it is on MySQL, please refer to this KB.

If the above possible causes is not the cause on your end, you might want to create a support ticket at our support channel so that we could review your instance log and information in private.

Hope it helps.
