Ok here a code snippet to demonstrate the issue. If I uncomment Thread::Pool I don't see anything in the web browser, but the logs don't show any error. As soon as I comment it out I see the expected template display:
CGI code
#!/usr/bin/perl -w
use strict;
use CGI;
#use Thread::Pool;
use Template;
my $q = new CGI;
print "Content-type: text/html\n\n";
my $file = 'template.html';
my $vars = {
message => "Hello World\n"
};
my $template = Template->new({
INCLUDE_PATH => $ENV{DOCUMENT_ROOT} . '/t
+emplates'
});
$template->process($file, $vars)
|| die "Template process failed: ", $template->error(), "\n";
template.html:
<html lang="en">
<head>
<title>Template Thread Test</title>
</head>
<body>
This is a test, [% message %]
</body>
</html>
