Subject [jira] Commented: (SOLR-2124) SEVERE exceptions are being logged for expected PingRequestHandler SERVICE_UNAVAILABLE exceptions
Date Fri, 15 Oct 2010 16:04:32 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12921419#action_12921419
] 

Shawn Heisey commented on SOLR-2124:
------------------------------------

I looked at the 1.4.1 source, since that's what I am using at the moment.  I changed one line
in RequestHandlerBase.java.  Original line:

SolrException.log(SolrCore.log,e);

New line:

SolrException.logOnce(SolrCore.log,null,e);

The modified 1.4.1 source successfully compiled and passed all junit tests.  It'll take me
a while to get to the point where I can try it out to see whether it actually makes things
better.  I'm not qualified to check whether this change will cause problems elsewhere.  This
change does not address Hoss's parenthetical comment regarding the logged property defaulting
to true.

a SEVERE error...
