in reply to memory usage and leakage

when running on SuSE with perl 5.10.0 I get the following data:

Did you try using a different version of Perl? I don't follow p5p but I know by experience that 5.10.0 had some memory leaks that were fixed in 5.10.1 and above.

perldelta for 5.10.1 in particular lists a weak reference to a hash would leak.

Good idea. I have not tried yet as our production perl is 5.10.0 and I cannot change that any time soon. Besides it seems the leak is in one of the modules I am using.	[reply]

The leak in Perl can show up in one of the modules. It happened to XML::Twig, I had a couple of reports that it was leaking, and when I looked into it, it turned out to be a Perl problem. updating Perl to 5.10.1 fixed the problem for everyone.	[reply]

Load perldeltas - every perl*delta in one file, and search (Ctrl+F) for leak, its amazing what you can find :) http://pastehtml.com/view/1e8ud19.html#p5140-Miscellaneous_Memory_Leaks http://pastehtml.com/view/1e8ud19.html#p5101-Selected_Bug_Fixes	[reply]
