Неуспешно изпълнение в perl dbi

Част от кода. Скриптът трябва да се превърне в демон, да се свърже с две бази данни и постоянно да проверява някои полета. Но получавам грешка. Дневник DBD::Pg::st execute failed: SSL connection has been closed unexpectedly at ./remote_imap.pl line 55.

Дневникът на базата данни е празен.

my $daemon = Proc::Daemon->new;
Proc::Daemon::Init({
      work_dir     => '/home/olex/develop',
      child_STDOUT => '/home/olex/develop/output.file',
      child_STDERR => '+>>debug.txt',
      pid_file     => 'remote_imap.pid'
      });
if (Proc::PID::File->running({dir=>'/home/olex/develop', verify=>1})) {
print "Already running\n";
exit 0;
}
my @kids = (0..3);

my $dbh = DBI->connect("dbi:Pg:dbname=$dbname;host=$dbhost;port=$dbport", $dbuser, $dbpass,
                      { RaiseError => 1
                      , AutoCommit => 0 })
    or die $DBI::errstr;
my $dbh_ag = DBI->connect("dbi:Pg:dbname=$dbname;host=$dbhost_ag;port=$dbport", $dbuser, $dbpass,

                 }
         push @childs, $kid_pid;
                 }

  my @params;
  $params[0] = 2; #DB_USERS_REMOTE_STATUS_PROCESSING
  $params[1] = 1; #DB_IN_QUEUE_STATUS_NEW
  my $childs_proc = join(',', @childs);
# Fetch new records
  my $q = "select id from queues.queue_in where status=? and user_remote_id>? order by date_create asc";
  my $sth_ag = $dbh_ag->prepare($q);
  my $rv_ag = $sth_ag->execute($params[1], 0);
  my $id = $sth_ag->fetchrow_array();
  print $id, "\n";

  sleep(0.0001);

}
$dbh->disconnect();
$dbh_ag->disconnect();

Ако изтрия този код, работи правилно.

foreach $kid_pid (@kids) {
$status = $daemon->Status($kid_pid);
if (!$status){
      $kid_pid = $daemon->Init( { 
                    work_dir     => '/home/olex/develop',
                    pid_file     => 'kid_pid.pid',
                    exec_command => 'perl /home/olex/develop/remote_imapd.pl',
                 } );
                 }
         push @childs, $kid_pid;
                 }

perl v5.18.2 postgresql v8.4

Какъв може да е проблема?
