I have created hashs of hashs for a very large data file just trying to use my 8GB RAM. But it has a out of memory problem. My code is fine for smaller size of data, but not the whole data (20000000 lines).
the major chunk of code is as below:
print "Fished establishing hashs.\n";
I don't think the problem resulted from limited memory since it reported "out of memory" when it only used 40% of my 8GM ram.
Could any perl guru help me resolve this problem? Thanks.
