Hi Helix, Thanks for your help so far.
Just picked up this in the dspsace.log. Is it of use in pinpointing the issue? 2013-08-06 13:58:18,767 INFO com.atmire.statistics.export.ExportUsageEventListener @ Robot (Mozilla/5.0 (compatible; Baiduspider/2.0; +http://www.baidu.com/search/spider.html)) accessed Ferromagnetic Microswimmers.pdf/null 2013-08-06 13:58:20,441 ERROR org.dspace.app.xmlui.cocoon.DSpaceCocoonServletFilter @ Serious Error Occurred Processing Request!

Yes, it hasn't changed: https://github.com/DSpace/DSpace/blob/dspace-1.8.2/dspace-xmlui/dspace-xmlui-api/src/main/java/org/dspace/app/xmlui/cocoon/MetadataExportReader.java#L187 > It is an export of a community, containing several collections/items. > It has had its name changed recently That shouldn't matter. Let's try to find out whether the problem is in the CSV exporter or in Cocoon. Call the CSV exporter from the command line like this (replace 123456789/123 with the handle of your community): [dspace]/bin/dspace metadata-export -f export.csv -i 123456789/123 Regards, ~~helix84 Compulsory reading: DSpace Mailing List Etiquette https://wiki.duraspace.org/display/DSPACE/Mailing+List+Etiquette ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
