Hi all,

SCENARIO:
- oracle 9i RAC installation on linux RedHat

java swing application using Jsdk1.4.2_06 deployed on HP machine, both resident on the same LAN. the application cycle on polling on another windows machine via FTP and save records on oracle
oracle JDBC driver used : ojdbc14-10-1-0-1-0.jar

after a quite long period the application is running we are experiencing the following exception :

Stack: java.sql.SQLException: IOException: End of TNS data channel

	at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
	at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)
