FYI, I'm running cygwin on Win2K Pro and don't appear to have any memory
leaks, or any problems in general. My machine pretty much stays up 24/7 (I
do occasionally reboot out of force of habit.) I've got no personal FW, am
running AVG Anti Virus 6.0 and a pretty mixed bag of Windows services and
cygwin services. And I use Perl daily :) with no problems (albeit web server
cgi scripts.)
Here are some of my machine details:
