Hi All,

We have SOLR 4.1 Master and Replica setup using Tomcat service . Lately I am seeing \
below two exceptions in Master server logs.


*        Socket Connection

I don't have much expertise on the Tomcat exceptions. Could someone tell me why these \
errors has occurred and how this can rectified ?

Thanks
