What I didn't publish is the following in my code: just after:

$kid = fork;
[download]

I am doing the following:

$dbh = DBI->connect("DBI:mysql:DatabaseName;host=127.0.0.1;mysql_serve
+r_prepare=1",'root','pass',{AutoCommit=>1}) or die $DBI::errstr;
[download]

It works just fine for me using the fork emulation. Can you perhaps may be give me an example of using multiple Database handles and threading server with IO::Socket. Thanks a lot for your answers, you are really helping me.
