Well again, without knowing anything about your system, what tasks you have running, how many users, and the structure of your script, it is very difficult to say.  Are you reading all 11 files at once, and how big are the variables you are reading?  If you are reading in large variables and performing calculations to create derived variable from which you plot results, perhaps deleting the original variables before calling gsn_open_wks()?

I'm using eleven data files and many processes, which should require memory, but how could fix it? any suggestion?

Hi,

That's coming from a line of code that tries to test that the output directory for the plot exists and is writeable.  It does so by creating a subprocess to perform the tests.  The errno=12 indicates there was not enough memory on your system to create the child process.  Without knowing anything about your system, its difficult to say why, but perhaps too many concurrent users or too many running processes, or memory-intensive processes?
