Do you have a derby.log from when this occurs? Do you have the complete exception stack trace with nested exception?

> We are sporadically getting "Cause: java.sql.SQLNonTransientConnectionException: A network protocol error was encountered and the connection has been terminated: the requested command encountered an unarchitected and implementation-specific condition for which there was no architected message" and we will have to restart the server.  We also have received "Cause: java.sql.SQLNonTransientConnectionException: Network protocol exception: actual code point, 4,692, does not match expected code point, 9,224.  The connection has been terminated.; nested exception is com.ibatis.common.jdbc.exception.NestedSQLException: " which also required a restart.
