Trouble Using display Dspace on Omeka S

[Patm]

We got the following error using the DSpace connector:

2021-03-08T19:13:48+00:00 ERR (3): Laminas\Http\Client\Adapter\Exception\TimeoutException: Read timed out after 10 seconds in /srv/www/adhc/lib/vendor/laminas/laminas-http/src/Client/Adapter/Socket.php:650

Does anyone have any ideas?

Thanks!!

Hi! I assume this is happening when trying to import–can you please share your module configuration including the site URL and collection you’re importing?

[Patm]

Yes we are!
I’ve attached our info below!

The first thing I’d try is lowering the Limit–the default is 100, and 2000 is quite high. I was successfully able to import the collection with the default setting, and had it fail in the same way when I set the limit to 2000.

The background here is that “Limit” is the number of records the DSpace Connector will request at once. The error you’re seeing is a timeout error: the DSpace server you’re connecting to took too long to respond.

Lowering the Limit reduces the strain on the DSpace server by asking it for fewer items at a time, but doesn’t affect your ability to do large imports: when the limit is lower, we simply make more requests, but will still get all the items.
