[...] :Please advise how to resolve this issue. Thanks Most likely you are encountering a bug either in the perl program you are running or in perl itself. If it is a bug in perl itself, it has probably been fixed by now - try downloading and installing a more recent version of perl (the latest is 5.8.0) and see if the problem persists. If the problem is in your code, try first to determine where in the code the problem occurs by adding diagnostics - the bug may become obvious when you do that. If not, try step by step to cut down the program to the shortest possible example that gives the error, and then send that example to this same address along with the output from "perl -V". One thing that can often cause this sort of problem is if you use a reference as the subscript of an array, eg: my $arrayref = [ "array", "ref" ]; my $element = @array[$arrayref]; Perl coerces any expression used as an array index to an integer; a reference, when coerced to an integer, returns the value of its location in memory, which is usually a large number. Using this large number as the index into the array then causes perl to try to extend the array to be large enough, which can cause the out of memory error you are seeing. This is just one example of how things can go wrong - you need to look at the code you are running. Hope this helps, Hugo van der SandenThread Previous
