Re: Perl Threads and Memory Leaking

Data point alpha netbsd 2.1 perl 5.10.0

(just remembered that I've access to a box differing a bit from the setups tested above. First col is actually SIZE, 2nd is RES; running niced and with lowered count intervals to be more courteous to the hoster)

^c as I don't want to hog that old server for too long.

It affects Linux and at least one BSD (Alpha, 64bit AFAIR; not just Intel...), both 32 and 64bit for Linux; with Perls for these hosts ranging from 5.8.8 to at least 5.10.1..

Not nice.

I can't find a linux box with a recent perl version where this doesn't occur. Perhaps submitting a bug report is in order. Perhaps we can get some clarification.	[reply]
