I appear to be running into a memory leak in IO::Socket which I can't fix. The following example: #!/usr/bin/perl -w use strict; use IO::Socket; my $RemoteHost = 'localhost'; while (1) { my $Socket = new IO::Socket::INET(PeerAddr => $RemoteHost, PeerPort => 80, Proto => 'tcp', Type => SOCK_STREAM, ); $Socket->close(); undef $Socket; } I can't see anything obviously wrong with this.

1.1603 Any hints what I might be doing wrong, or how I could fix this? I tried looking through the P5P archives, asked dejanews and EFNet #perl even (I was that desperate;) but only found a post from someone who also ran into this problem. I assume IO::Socket as included with the default distribution is fairly old, since the e-mail address of yours in perldoc IO::Socket bounced? Thanks in advance.

I cannot replicate this on OS X using 5.4.5 and 5.5.4. Are you still having this problem in newer Perls and versions of IO?
