Hi, Two potential memory leaks have been reported recently: - https://issues.apache.org/jira/browse/LUCENE-7647 - https://issues.apache.org/jira/browse/LUCENE-7657
These are annoying bugs so I would like to do a 6.4.1 release that includes these fixes. If this is fine with everyone, I'll commit the patches attached to these issues later today and will also look at whether there are other bug fixes that should be backported. I'm currently thinking of building the RC next Monday to give CI some time to ensure these patches do not cause problems. Adrien
