Per Steffensen created SOLR-4031:
------------------------------------
Summary: Rare mixup of request content
Key: SOLR-4031
URL: https://issues.apache.org/jira/browse/SOLR-4031
Project: Solr
Issue Type: Bug
Components: multicore, search, SolrCloud
Affects Versions: 4.0
Reporter: Per Steffensen
We are using Solr 4.0 and run intensive performance/data-integrity/endurance
tests on it. In very rare occasions the content of two concurrent requests to
Solr get mixed up. We have spent a lot of time narrowing down this issue and
found that it is a bug in Jetty 8.1.2. Therefore of course we have filed it as
a bug with Jetty.
Official bugzilla: https://bugs.eclipse.org/bugs/show_bug.cgi?id=392936
Mailing list thread:
http://dev.eclipse.org/mhonarc/lists/jetty-dev/threads.html#01530
The reports to Jetty is very detailed so you can go and read about it there. We
have found that the problem seems to be solved in Jetty 8.1.7. Therefore we are
now running Solr 4.0 (plus our additional changes) on top of Jetty 8.1.7
instead of 8.1.2. You probably want to do the same upgrade on the Apache side
sometime soon.
Alt least now you know what to tell people if the start complaining about mixed
up requests in Solr 4.0 - upgrade the Jetty underneath to 8.1.7 (or run tomcat
or something)
