Hi, Since we recently went live with v1.6.2 I've noticed a large number of the following in our logs:
------------------------------------------- 2011-03-08 00:14:16,592 ERROR org.dspace.statistics.SolrLogger @ Service Unavailable Service Unavailable request: http://127.0.0.1:8080/solr/statistics/update org.apache.solr.common.SolrException: Service Unavailable Service Unavailable request: http://127.0.0.1:8080/solr/statistics/update at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:343) at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:183) at org.apache.solr.client.solrj.request.UpdateRequest.process(UpdateRequest.java:217) at org.apache.solr.client.solrj.SolrServer.commit(SolrServer.java:85) at org.dspace.statistics.SolrLogger.post(SolrLogger.java:247) ... ------------------------------------------- They occur seemingly randomly, sometimes every few minutes, and sometimes every hour or so (so possibly related to load?). SOLR stats are working fine otherwise - I can see Usage Events being successfully logged between failures, and "View Statistics" for items shows views and downloads being counted (but presumably not all, due to the frequent failures?). I searched the archives and found a couple of other mentions of the problem, but no hint of a solution beyond making sure your SOLR webapp is reachable (which mine appears to be generally, and access also tested from the command line with curl). Anyone have any ideas? I also wondered if the optimisations discussed here, http://atmire.com/statistics_performance.php, might fix this issue? Any assistance/pointers welcome.
