Subject [jira] Commented: (SOLR-2235) java.io.IOException: The specified network name is no longer available
Date Wed, 17 Nov 2010 00:53:21 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12932740#action_12932740

Antony Bowesman commented on SOLR-2235:
---------------------------------------

I've just been made aware of this issue also (non SOLR), also deployed with Tomcat, but Tomcat
is not part of the thread stack where the problem is seen.  It's with Lucene 2.3.2 and Tomcat
6.  It seemed to occur for a week at the end of October, but has not been seen since.

> ===========================
> The error stops when we restart Tomcat.  We are using a file server to store the actual
index files, which are not on the same machine as Solr/Tomcat. We have checked and confirmed
with the network team that there was no issue. Can some one help us to fix the issue
