Almost all uses of glob can be replaced by other fairly simple substitutes that consume less memory, but you'll have to show what you (the module) is using it for. Examples of inputs and corresponding outputs to that function would probably get you a solution to the problem.
BTW: Does "lakh" mean 100,000?

I wonder if you might be running out of C stack space. I believe glob builds all the results up front, even if you use the iterator form. The solution would be to write an alternative to glob that generates the results one at a time or an alternative that generates the results in Perl memory rather than on the C stack.

Providing information regarding the problem may help
"Out of memory" errors generally refer to two possible problems: the Random Access Memory (RAM) in the computer that was responsible for the execution of the Perl program became exhausted, or the memory of the user who executed the program became exhausted. ;)
Which Perl program led to the error/warning? What type of system are you running the program on? What is the name of the function that creates "thousands of combinations of values using 'glob'", and which package does that function originate from?

Hi Steve,
There is this function called genCombinations which generates several combinations for a set of values using glob. Ex:
f1= (1,2) f2 = (3,4,5)
No. of unique combinations = 6
1,3 1,4 1,5
2,3 2,4 2,5
Fields can be several tens and they can also have a range of values like:
f1 = range(0 to 100)
f2 = values(2,5)
In such case no. of unique combinations will be 200.
So i used a glob to create these combinations.
@arr = glob{ (0 to 100),(2,5) };
How else can i create these combinations so that the Out Of Memory error vanishes!
