Subject [jira] Commented: (SOLR-2124) SEVERE exceptions are being logged for expected PingRequestHandler SERVICE_UNAVAILABLE exceptions
Date Sat, 18 Sep 2010 02:11:33 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12910890#action_12910890
] 

Hoss Man commented on SOLR-2124:
--------------------------------

At first glance, this seems like a fundemental problem with how the "logged" property of SolrException
is used ... logOnce is hte only method that ever tests it, the other log methods blindly set
it to true and proceed with logging.

if this is intentional, then i suspect there are lots of places in the code that are using
"log" when they are suppose to be using "logOnce"

(It also makes no sense to me that the "logged" property is defaulted to "true" in several
constructors)
