-----------------------------------

             Summary: DIH postgres connections are not closed
                 Key: SOLR-4747
                 URL: https://issues.apache.org/jira/browse/SOLR-4747
             Project: Solr
          Issue Type: Bug
          Components: contrib - DataImportHandler
    Affects Versions: 4.2
         Environment: Solr on CentOs 6.4 within jboss, debian 7.0 postgres 
server
            Reporter: Remko Kuipers


I use DIH to create an index for a number of postgres databases. These 
databases all contain an identical schema/table setup. The config looks like 
<entity rootEntity="false"><entity/><entity/></entity> repeated for each 
datasource. The readonly flag is set to true on the subentity objects. For each 
database solr creates three connections. These connections remain active as 
"idle in transaction" until the indexer is finished. As the number of databases 
times three exceeds my max_connections setting in postgres the indexer 
inevitably fails halfway through with a no more connections available error.
