I am running a fortran program on a linux system, which gradually allocates memory throughout the run. It uses quite a lot of memory (~2GB). I get the following error some way into the program:
115393462:heap block overflow; -heapz too large
run has crashed
I tried setting the heapz size higher by running it as
./program_name -heapz 128M
but this had no effect. I have no idea what a heap is at all. Does this mean I have used up all the memory? I am running on a single processor.
Would be vv grateful for any assistance!
