Podczas wysyłania polecenia do baz danych jest takie 20%, że pakiet nie dochodzi i crashuje mi serwer mc. Odbieranie rezultatów działa nie zawodnie z tego co widzę, ale to już tak średnio oraz na dodatek ten crash serwera.

	  public void ExecuteCommand(String command)
	  {
	    try
	    {
	      if (this.connection.isClosed()) {
	        Connect();
	      }
	      Statement st = this.connection.createStatement();
	      st.executeUpdate(command);
	    }
	    catch (SQLException e4)
	    {
		  System.out.println("[MySQLAPI] Wystapil blad numer e4");
	      e4.printStackTrace();
	    }
	  }

Jakieś pomysły lub sugestie dlaczego mi crashuje serwer i nie odbiera mi czasami pakietu ?
