我使用jtds 1.3.1连接到MSSQL Server 2008 SP3。我在3个单独的线程中创建3个PreparedStatements并向它们添加查询。当我执行PreparedStatements时，我得到了这个例外：
java.sql.BatchUpdateException: I/O Error: Connection reset by peer: socket write error
at net.sourceforge.jtds.jdbc.JtdsStatement.executeBatch(JtdsStatement.java:1091)
at de.mvn.gotdb_mvn.Main.main(Main.java:181)
请帮我解决问题。这是我的代码：

importer.openConnection();
final Connection connection = importer.getCon();
importer.createNewTables();

falldata_stmt.setString(4, line[19]);

OpenConnection方法：
public void openConnection(String p_propertys)
