Hi list, I have looked into the CLOSE_WAIT problem and created an issue with a patch to fix this. A search for CLOSE_WAIT shows that there are many Apache projects hit by this problem.
https://issues.apache.org/jira/browse/SOLR-3280 Can someone recheck the patch (it belongs to SnapPuller) and give the OK for release? The patch is against branch_3x (3.6). Regards Bernd
