Shawn Heisey commented on SOLR-4191:
------------------------------------
Can anyone tell me whether this indicates it's a GC problem? I am interpreting
the haproxy log to mean the ping query started at 16:37:34. One thing I do not
know - does the GC log timestamp indicate when the GC *started* or *ended*? If
it's the start time, then this is definitely a GC problem - specifically, the
GC happening on the other shard server.

> Environment: solr-impl 4.1-SNAPSHOT 1421496 - ncindex - 2012-12-13

> 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:

> null:org.eclipse.jetty.io.EofException
> ERROR - 2012-12-13 18:17:01.982; org.apache.solr.common.SolrException;

> /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.
