-----------------------------
Resolution: Duplicate
> SocketExceptions no longer trigger retries when processing distributed updates
> ------------------------------------------------------------------------------
>
> Key: SOLR-6983
> URL: https://issues.apache.org/jira/browse/SOLR-6983
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.7
> Reporter: Lindsay Martin
>
> Our production Solr cluster is frequently placing replicas into
> leader-initiated recovery whenever a "java.net.SocketException: Connection
> reset" is thrown when processing distributed updates.
> This problem surfaced after upgrading from Solr 4.6.1 to Solr 4.10.2. In the
> old version, a retry was attempted whenever a SocketException was encountered
> when a leader was updating a replica. After the upgrade to Solr 4.10.2, this
> retry mechanism no longer occurs.
> Here is an example stacktrace:

> The underlying SocketException may be related to
> [SOLR-6931|https://issues.apache.org/jira/browse/SOLR-6931] and the disabling
> of the HttpClient stale connection check.
> It appears that the retry logic was removed from the SolrCommandDistributor
> starting with 4.7 to address
> [SOLR-5509|https://issues.apache.org/jira/browse/SOLR-5509]. See
> https://svn.apache.org/viewvc/lucene/dev/trunk/solr/core/src/java/org/apache/solr/update/SolrCmdDistributor.java?r1=1546672&r2=1546164&pathrev=1546672
> Is there any way the retry logic could be restored for Solr 4.10.x ?
