sql server - java.sql.BatchUpdateException: I/O Error: Connection reset by peer: socket write error -


i connect mssql server 2008 sp3 jtds 1.3.1.i create 3 preparedstatements in 3 seperate threads add querys them. when execute preparedstatements exception:

 java.sql.batchupdateexception: i/o error: connection reset peer: socket write error     @ net.sourceforge.jtds.jdbc.jtdsstatement.executebatch(jtdsstatement.java:1091)     @ de.mvn.gotdb_mvn.main.main(main.java:181)

please me solve problem. code:

the openconnection method:

   public void openconnection(string p_propertys)    {      try{       class.forname("net.sourceforge.jtds.jdbc.driver");      string url="jdbc:jtds:sqlserver://lb236/checkpointdb;logintimeout=30;sockettimeout=1800";      string user ="jadmin";      string pw="jadmin123";      con = drivermanager.getconnection(url,user,pw);      }catch(exception e){e.printstacktrace();}    }
