Hi Following a post I posted in stack overflow ( ) I am using IO::Socket::INET6 (Perl). Versions: Linux Perl version: 5.16 Module Version: 2.69 (INET6) | 1.34 (Socket) I am using this base code: our %openSockets;sub forward_message{ my ($message,$ip,$port,$proto) = @_; my $key = "$ip:$port:$proto"; my $socket = $openSockets{$key}; unless ($socket && $socket->connected()){ $|=1;#Setting autoflush $socket = new IO::Socket::INET6( PeerAddr => $ip, PeerPort => $port, Proto => $proto ) || die "Can't create socket [$key]"; $openSockets{$key} = $socket; } #autoflush $sock 1; $socket->say($message); #$socket->flush();} The "forward_message" function is called every 1-5 seconds based on input my application receives and send a message to a destination (ip|port|protocol Trio) At first the message are sent individually but after some time the messages are buffered and sent in big chunks The bug occurs when I try to send messages via UDP (so this is not a TCP buffering) As you can see in the attached code, I was trying all kind of stuff i found online. Finally - what that "solved" the problem is when I called "$socket->flush(); " This ensure the message being sent - avoiding auto flush Important to say - this is not a threaded application. So calling manually to flush will work on this case

Actually this is the wrong queue. This should have been opened here:
I have moved this ticket into IO-Socket-INET6
