Re^2: Socket hang. (Windows or Perl? Solutions?)

If you ^C it when it stops and try to re-run the script on the same port immediately, does it block/lock/hang much more quickly?

If you then immediately run it using a different port number, does it then demonstrate the original behaviour again?

Thanks.

Same port worked for just 3 servers before rehanging. New port worked like a fresh instance. `>perl temp.pl -port=12345 server:3911 client:3911 cycles: 88.886/secTerminating on signal SIGINT +(2) >perl temp.pl -port=12345 server:3 client:3 cycles: 0.250/secTerminating on signal SIGINT(2) >perl temp.pl -port=12346 server:3912 client:3912 cycles: 97.800/secTerminating on signal SIGINT +(2)` [download]	[reply] [d/l]

Same port worked for just 3 servers before rehanging. New port worked like a fresh instance. Yes. That mirrors the behaviour I'm seeing. If you retry the original port some time later--I haven't tied down how much later yet--it "recovers", which suggests this is a timeout issue, but I am at a loss to see where else to apply timeouts? I;ve no reports of the same behaviour under *nix (yet), so this may be a windows-only problem. I guess I'll have to write the equivalent code in C to isolate whether it is windows itself, or Perl on windows. Which is a pain in the butt.
