Hi guys,

I am using Apache Solr with Drupal 7. It's been installed on this site for about 5 months and suddenly last night we started seeing these errors in the admin pages.

Warning: simplexml_load_string() [function.simplexml-load-string]: Entity: line 1363: parser error : Premature end of data in tag stats line 1329 in DrupalApacheSolrService->setStats() (line 195 of /afs/asu.edu/it/drupal/qa/wsi/sites/all/modules/contrib/apachesolr/Drupal_Apache_Solr_Service.php).

Any ideas? from the research i've done, a lot of people suggest it's a core issue in the common.inc file with feof, but d7 isn't using that any more and all those issues were for d6.

This doesn't break my site, solr works fine and retrieves results fine, so it's not critical, but it is certainly odd.

Please look at the actual XML - maybe the stats.jsp page is timing out?

Yes, the stats.jsp page is timing out.

Do you have a very large index or a lot of cores?

Yes, these indexes contain over 250,000 records.

If you are willing to rebuild Solr, you can patch stats.jsp to return only the info Drupal needs. That's the work-around we've had to use in production for Solr with many cores.

You may use the attached patch for Solr 1.4 under the terms of the Apache Software License 2.0. More or less the same works for Solr 3.5.
