Hi Andy,<br>
<br>
I tried to use threads and it did not worked for me (maybe because of<br>
non safe thread modules I am using) so I use fork in a production<br>
application and it works good. I have some issues some times with<br>
MySQL that I have not fixed yet but they do not happen very often.<br>
<br>
This is an example of how I use it:<br>
<br>
sub execute {<br>
<br>
# These 2 lines below were to eliminate the error that I mentioned<br>
before. It did not eliminated them just reduce them<br>
my $dbh = database();<br>
$dbh->{InactiveDestroy} = 1;<br>
<br>
my $pid = fork();<br>
<br>
if ($pid) {<br>
# This is the parent (Dancer) in case you want to do something here<br>
debug “Process started with PID $pid\n”;<br>
<br>
} elsif ($pid == 0) {<br>
# This is the child, here is where I do all I need<br>
$template = ...<br>
} else {<br>
debug “Could not fork: $!\n”;<br>
}<br>
<br>
# I have a variable to know if I’m running this sub from the web or from CLI<br>
if ($cli) {<br>
my $output = waitpid($pid, 0);<br>
print “The process finish with output: $output”;<br>
}<br>
<br>
return $template;<br>
}<br>
<br>
This is just an example, not the entire code. If someone has a<br>
suggestion or improvement, it is welcome.<br>

Surely you need an exit() in there somewhere for the child process, otherwise you'll end up with lots of web server threads?<div class="HOEnZb"><div class="h5"><br>
