Tried what you suggested, changed it a little though to

while(1) {
    use strict qw/refs/;
    use warnings FATAL => 'syntax';
    
    my @ready = $selSock->can_read(10);
    unless (@ready) {next};
[download]

so that it wouldn't die if no clients connected. But anyway, and had no effect that I could see. Thanks for the suggestion though!
