Hi all, Starting around last Tuesday users have been experiencing problems with submitting their theses to our DSpace (v5.5, PostgreSQL, Ubuntu 14.04 with DS 5.6 and 5.7 patches). What happens is they complete the submission information (name, abstract, file upload, license agreement, etc.) but when they press the final submit button after the last step it takes 1-2 minutes to either submit successfully or, most frequently, to get a 500 error.
We haven't touched the source code in the last month, so we're not sure what happened as of last week. Looking at the logs, I have noticed a few things: - We are/were getting lots of traffic from Google, Bing and Baidu spiders - I have since implemented the Crawler Session Manager Valve in Tomcat7, which was mentioned by Alan Orth at https://wiki.duraspace.org/display/cmtygp/DCAT+Meeting+April+2017. We are now getting fewer sessions reported in Tomcat, but the upload/submission problem persists. - In /dspace/log/dspace.log.<date> we are getting lots of "Failed DNS Lookup for IP:<IP address>". - In /dspace/log/dspace.log.<date> were are getting lots of "ERROR org.dspace.app.xmlui.cocoon.DSpaceCocoonServletFilter @ Client closed the connection before file download was complete" - In /dspace/log/cocoon.log.<date> we are getting lots of errors like "Caused by: org.xml.sax.SAXException: An error was encountered while processing the 'aspect.general.PageNotFoundTransformer' Wing based component: org.dspace.app.xmlui.aspect.general.PageNotFoundTransformer" The odd thing is that the user's submission usually does go through successfully, even if the "Internal Server Error" page comes up. If they return to the home page, logout and login and go to their submissions they will set it there. Unfortunately, most people don't know to do that and keep resubmitting their thesis. Any pointers in the right direction are greatly appreciated!
