Question: Stack limit error

Hi all I've a program running that has been stopped with the error Execution stopped: Stack limit reached. at that time the program was using memory used=480073.6MB, alloc=594.8MB, time=16330.02 The host computer has 16 CPUs and 50Gb of Ram, so I don't think the problem is the memory... Any hints? Thanks Salvo ps: I've found an old discussion about this problem, but it was very old (2005, M9) so I've thought I could open a this one.
Please Wait...
