Shawn Heisey commented on SOLR-4191:
------------------------------------
According to this (admitttedly outdated) document, GC timestamps are at the
start of the collection, so this is apparently a problem caused by GC pauses.

If I add CMS incremental mode, would that help?
Remaining problem for this issue is whether or not it would be possible to
change the loud exception into a log indicating that the client connection has
been closed - which might require cooperation from the servlet container.

> I am getting the following exceptions in quick succession in the solr log
> when /admin/mbeans is accessed at the moment that an update/commit is
> happening:
> ERROR - 2012-12-13 18:17:01.930; org.apache.solr.common.SolrException;
> null:org.eclipse.jetty.io.EofException
> ERROR - 2012-12-13 18:17:01.982; org.apache.solr.common.SolrException;
> null:org.eclipse.jetty.io.EofException
> WARN - 2012-12-13 18:17:01.984; org.eclipse.jetty.server.Response; Committed
> before 500 {msg=Broken pipe,trace=org.eclipse.jetty.io.EofException
> WARN - 2012-12-13 18:17:01.984; org.eclipse.jetty.servlet.ServletHandler;
> /solr/s0live/admin/mbeans
> java.lang.IllegalStateException: Committed
> I will attach the full solr log. Before SOLR-4135 was fixed, I got a *lot*
> of those exceptions, but these were far less common. Now these appear to be
> the only thing I am getting in my logs, which log4j is logging at WARN.
