Re: [EP-tech] EPrints upload error on files over ~130k

I would disable SELinux temporary to see if it is the guilty. What was the fix in 2014?

Hi Kelly,

Sorry, I misread your subject line as "upload error on file of ~130k" for some reason.  I do no believe that there would be any restriction prevent files over 130k being uploaded.  The default limit is 1GB.  This may still be the tmp directory issue I described previously, as sufficiently small files I suspect will be written directly to the correct place on the filesystem, whereas anything over this size will be transferring the file piecemeal and therefore will collect in the tmp directory and only be moved once the upload is complete.

Hi Kelly,

This could be one of a number of issues.  The first thing I should check with you is if this is a one off issue with a particular file or EPrint record or if it is affecting you uploading any files to your repository?

My best guess on the issue, would be that you either need to configure EPrints temporary directory or ensure that the temporary directory you have specified exists and is writeable to by the webserver (Apache).  (However, I cannot see why this would have suddenly changed if it was working before). Typically, I would add the tmp directory configuration to your archive's session.pl (e.g. /opt/eprints3/archives/nau/cfg/cfg.d/session.pl) in session_init and reload Apache.  Something like:

$c->{session_init} = sub
        my( $repository, $offline ) = @_;

        $ENV{'USER'} = 'eprints';
        $ENV{'HOME'} = '/home/eprints';
        if ( -d "/opt/eprints3/tmp/" )
                $ENV{'TMPDIR'} = '/opt/eprints3/tmp/';

The reason I suspect it is this issue, is because RHEL 7 will not by default allow EPrints to write to /tmp/ if the Apache user is set to eprints in /etc/httpd/conf/httpd.conf, as is generally recommended.  Therefore, you need to specify EPrints' own tmp directory, the above example uses /opt/eprints3/tmp/.  If you have this configuration in place, you should also make sure that /opt/eprints3/tmp/ has the following permissions and user/group ownership (using "ls -la /opt/eprints3/tmp/" and checking the first line of the output):

drwxrwsr-x 12 eprints eprints    77824 Aug 28 21:35 .

Even if this is the same as above (bar the size of the directory and the modified date), I would further recommend clearing out the /opt/eprints3/tmp/ as it will not be cleared on reboot like /tmp/ and may be using up unnecessary space. Typically tasks clear up stuff they have put in EPrints' tmp directory but over time there will be the odd thing that does not get cleared and over months and years this may start to waste a significant amount space.

We’re currently having a problem uploading files over about 130 kb to our institutional repository. We’re running EPrints 3.3.15 on Red Hat EL 7.5.

We get this error from the Quick Upload tool on the user homepage:

“Internal Server Error

The server encountered and internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.”

We get this error on the “Edit Item: Add a new document” screen:

“Request for https://openknowledge.nau.edu/cgi/users/ajax/upload_progress?progressid=2B24D4FBFE9742949458083C6D5C3228 failed: 404 Not Found”

Something similar to the second error has cropped up in 2014, and Jidai Yao addressed it, but that fix is already present in our code.

I’m early in the troubleshooting process (just getting to the server logs etc.) but if anyone has run across this and/or has any suggestions, I would be most grateful – we’ve just been advertising this service to our new faculty for the year, we’d rather not this be their first experience of it.
