Bug: replies mixed up with concurrent requests from the same host

[Kevin Perros]

Hello,

I'm new to the solr mailing list, and I have not used solr for much 
time, so I might be wrong.

I may have found a bug whose symptoms look that one in jetty 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=392936

I am using solr 5.0.0 (the one with the great packaging and deployment 
work :). I use a lucene index to store adio fingerprints for audio 
tracks, with a custom search system, which reads directly from leaf readers.

When I query solr with either curl or wget, with multiple parallel 
requests from the same client host to the server, the answers come mixed 
up. From my logs, I've seen that if I send 10000 requests, with a 24 
fold parallelism, I often get as an answer to a request, the answer to 
the first one.

Hence, I have tried to bypass jetty and launch the same batch work from 
"inside solr", by writing a dummy request that simulates the 10000 
requests, with the same 24 fold parallelism. In that case, everything 
works well.

I had already noticed that bug in mozilla. I have a bookmark folder with 
a bunch of test requests, and when I click on the "open all in tabs" 
button, the result from requests appears in the tab for another one, in 
a random fashion.

Regards,
Kevin
