Error on IDL processing when executing PolSARpro routines

i’m applying a boxcar filtering on Dual-pol Sentinel-1 data via IDL where are used PolSARpro routines. But it appears an error (without though canceling or stoping the whole procedure) saying that: “NOT ENOUGH MEMORY SPACE THE AVAILABLE PROCESSING MEMORY MUST BE HIGHER THAN 1000Mb - A processing error occured! Could not open configuration file”.
The space that I’m using is huge so there is no reason for this message to come up. I have to mention that the directory of data and software are located to another computer that are connected remotely.

I’ not much experienced in IDL but maybe you have to set the available memory manually:

However, this forum is about SNAP in the first place.
