: : I was wondering if anyone has found any resolution to this email thread?
As Grant asked in his reply when this thread was first started (December 2009)... >> It sounds like you are either using embedded mode or you have some >> custom code. Are you sure you are releasing your resources correctly? ...there was no response to his question for clarification. the problem, given the info we have to work with, definitely seems to be that the custom code utilizing the SolrCore directly is not releasing the resources that it is using in every case. if you are claling hte execute method, that means you have a SOlrQueryRequest object -- which means you somehow got an instance of a SolrIndexSearcher (every SOlrQueryRequest has one assocaited with it) and you are somehow not releasing that SolrIndexSearcher (probably because you are not calling close() on your SolrQueryRequest) But it relaly all depends on how you got ahold of that SOlrQueryRequest/SolrIndexSearcher pair in the first place ... every method in SolrCore that gives you access to a SolrIndexSearcher is documented very clearly on how to "release" it when you are done with it so the ref count can be decremented. -Hoss
