Since we pushed Solr out to production a few weeks ago, we've seen a
few issues with Solr not responding to requests (searches or admin
pages). There doesn't seem to be any reason for it from what we can
tell. We haven't seen it in QA or development.
We're running Solr with basically the example Solr setup with Jetty
(6.1.3). We package our Solr install by using 'ant example' and
replacing configs/etc. Whenever Solr stops responding, there are no
messages in the logs, nothing. Requests just time out.
We have also only seen this on our slaves. The master doesn't seem to
be hitting this issue. All the boxes are the same, version of java is
the same, etc.
We don't have a stack trace and no JMX set up. Once we see this
issue, our support folks just stop and start Solr on that machine.
Has anyone else run into anything like this with Solr?
Thanks.
Doug
