Subject Re: 9000+ CLOSE_WAIT connections in solr v6.2.2 causing it to "die"
Date Sat, 03 Feb 2018 00:47:47 GMT
I have seen a lot of CLOSE_WAIT in the past.
In many cases, it was that the client application was not releasing/closing
or pooling connections properly.

I would suggest you double check the client code first.

Arcadius.
