Hello, DSpace 4.3 JSPUI. We've had this problem for a few months now: a bad request to /browse causes Solr to start generating internal server errors. Here's the request that started it off earlier this morning:
http://www.myserver.com/browse?type=title&sort_by=1&order=ASC&rpp=20&etal=-1&null=&offset=14572 javax.servlet.ServletException: org.dspace.browse.BrowseException: org.dspace.discovery.SearchServiceException: Server at http://localhost/solr/search returned non ok status:500, message:Internal Server Error It was immediately followed by two more requests from the same IP address (54.175.208.220, somewhere in Amazon): http://www.myserver.com/handle/10393/11105/browse?type=title&sort_by=1&order=ASC&rpp=300&etal=-1&null=&offset=1800 javax.servlet.ServletException: org.dspace.browse.BrowseException: org.dspace.discovery.SearchServiceException: java.lang.Boolean cannot be cast to org.apache.solr.common.SolrDocument http://www.myserver.com/browse?type=title&sort_by=1&order=ASC&rpp=20&etal=-1&null=&offset=5778 javax.servlet.ServletException: org.dspace.browse.BrowseException: org.dspace.discovery.SearchServiceException: Error executing query After that, regular traffic (mostly from crawlers) also caused Solr to report internal server errors, every minute or so. Our repository has gone down unexpectedly overnight and on weekends (during cron jobs) and we think this might be related. Could the "&null=" parameter in those requests be the culprit? Seems fishy. Anyway, restarting Tomcat seems to clear it up, but we're wondering if this happens to anyone else and how to fix it.
