[ncl-talk] fatal:systemfunc: cannot create child process

[Rick Brownrigg]

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()?
