> as-is the SolrJ Commons HttpServer uses the multi-threaded http connection 
> manager. This manager seems to keep the connection alive for the client and 
> does not close it when the object is dereferenced.
> When you keep on opening new CommonsHttpSolrServer instances it results in a 
> socket that is stuck in the CLOSE_WAIT state. Eventually this will use up all 
> your available file handles, causing your client to die a painful death.
> The solution I propose is that it uses a 'Simple' HttpConnectionManager which 
> is set to not reuse connections if you don't specify a HttpClient.
