Public link download issues

user2 · August 9, 2019, 1:47am

Hi there,

We have recently been having issues sharing larger files (~200MB+) via public link from our owncloud instance as it now results in the download of the file stalling, partially completing or failing completely (network error) across all major browsers (Firefox, Chrome, Edge).

Rebooting the server had no effect and neither the owncloud nor apache logs produce any output while reproducing the issue. I have noticed a random apache process becoming defunct and disappearing every now and then but am not sure whether or not this was occurring prior to the problem.

This issue also appears to be related to the following unresolved issue: File Sharing (Link) download issues

I also suspect this problem might be related to the last OS patch that occurred a couple of weeks ago, however, this particular issue was not brought to our attention until recently. Here is the result of our ownCloud application server’s last OS patch (CentOS):

IMPORTANT NOTE: Our site has not been able to upgrade from a very old server version (v8.1.5) due to issues related to upgrading the database (even with the help of EE support). I am still waiting to hear back from EE support regarding our current issue but time is really of the essence for us (and there can be a significant time delay hearing back from support) so I’m kind of hoping the community might be able to come through for us here.

Steps to reproduce

Access a public link file/folder
Attempt to download a large file
Wait for it to fail

Expected behaviour

The download should complete 100% every time.

Actual behaviour

The download stalls, partially completes (the browser thinks it’s completed when it’s clearly not going by the filesize) or fails (Chrome reports: network error).

Any ideas?? Could this be an Apache/PHP/SMB issue??
