Hi,

I am seeing a lot of (reproducible) exceptions in my solr log file
when I execute streaming expressions:

o.a.s.s.HttpSolrCall  Unable to write response, client closed connection or we are shutting down

I have read up on the exception message and found
http://lucene.472066.n3.nabble.com/Unable-to-write-response-client-closed-connection-or-we-are-shutting-down-tt4350349.html#a4350947
but I don’t understand how an early client connect can cause what I am seeing:

What puzzles me is that the response has been delivered in full to the
client library, including the document with EOF.

So Solr must have already processed the streaming expression and returned the result.
It’s just that the log is filled with stacktraces of this exception that suggests something went wrong.
I don’t understand why this happens when the query seems to have succeeded.
Best regards,
Christian
