Greetings,
I'm wondering if anybody has experienced (and found root cause) for errors
like this. We're running Solr 3.6.0 with latest stable Jetty 7
(7.6.4.v20120524).
I know this is likely due to a client (or the server) terminating the
connection unexpectedly, but we see these fairly frequently and can't
determine what the impact is or why they are happening (who is closing
early, why?)
Any tips/tricks on troubleshooting or what to do to possibly minimize or
help prevent these from happening (we are using a fairly old python client
to programmatically access this solr instance).
