Subject Re: CLOSE_WAIT after connecting to multiple shards from a primary shard
Date Tue, 31 May 2011 17:38:29 GMT
Hi,

I think I already replied to this one on general@ or some other place.  Did you 
try the suggestion?  Please send any future replies to 
solr-user@lucene.apache.org instead of this dev@ list, which is for development 
of Lucene/Solr itself.
