Sometimes graph execution fails with error like this:

```auto

ERROR caused by: The size of data buffer is only 4096. Set appropriate parameter in defaultProperties file.

```

In such case you should increase the value of proper property, which is stored in defaultProperties file, which is located in “org/jetel/data/” subdirectory of CloverETL engine. You can create your own properties file with overridden properties you need to change only and run graph with -config switch. Full info can be found in [CloverETL framework run time constants](http://wiki.cloveretl.org/doku.php?id=compile%5Ftime%5Fconstants)
