Ravi Gidwani commented on SOLR-1769:
------------------------------------

Hi Noble:
                 Thanks for your comments. Here is more information:

1) I checked the solrconfig.xml . I am using the solr 1.4 with application specific changes.
I am attaching the solrconfig.xml for your reference.
2) All our solr servers (1 master, 2 slaves) are deployed on EC2 instances. They are all 64
bit instances. 
3) Running with  JDK 1.6 on Jetty 6.1.5

Here is the entire exception:
