Hello All,

I'm getting the following exception sporadically

java.sql.SQLException: Io exception: Operation interrupted
    at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
    at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:179)
    at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:333)
    at oracle.jdbc.dbaccess.DBError.check_error(DBError.java:1099)
    at
oracle.jdbc.driver.OracleResultSetImpl.next(OracleResultSetImpl.java:
309)
    at DBManager.getQueue(DBManager.java:200)

This happens in the following code

public static List getQueue(Connection connection){
        List queueEntries = new ArrayList();

        PreparedStatement pStmt = null;
        ResultSet rs = null;
        try{

            pStmt = connection.prepareStatement(qSql);
            rs = pStmt.executeQuery();
            while(rs.next()){
                QueueEntry qe = new QueueEntry();
                qe.setQueueEntryId(rs.getLong(1));
                qe.setEventId(rs.getLong(2));
                qe.setOid(rs.getLong(3));
                String value = rs.getString(5);
                if(value == null){
                    qe.setValue("");
                }else{
                    qe.setValue(value);
                }
                queueEntries.add(qe);
            }
            rs.close();
            pStmt.close();

        }catch(Exception e){
            cat.error("CATCH "+getStackTrace(e));
            queueEntries = null;
        }finally {
            try {
                if(rs != null){
                    rs.close();
                }
                if(pStmt != null){
                    pStmt.close();
                }

            } catch (SQLException e) {
                cat.error("FINALLY "+getStackTrace(e));
            }
        }

        return queueEntries;
    }

Any clue on what could be causing this exception would be of much help

Thanks and Regards

Chanchal
