Shawn Heisey commented on SOLR-4191:
------------------------------------
I changed the NewRatio to 8 while I was doing a full-import on all shards. I
did have one DOWN event on the load balancer during that import, but it was not
caused by a GC pause. It appears that the ping request took 7.7 seconds, which
is longer than the 5 second timeout on the load balancer check. Best guess is
that the I/O involved in indexing and merging made the ping take too long.
After the full-import finished, I removed NewRatio and instead went with
MaxNewSize. Here is my memory config now:
-Xms4096M -Xmx8192M -XX:MaxNewSize=256M -XX:+UseParNewGC
-XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:+CMSIncrementalMode
-XX:MaxTenuringThreshold=3
I will do another full-import later and then let it run uninterrupted for a few
days to see what happens.

> 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

> /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.
