Trying to get a sig child handler routine working. I'm using POE::Wheel::Run and used the sample close handler from the POE docs but it dies on me and kills off the job server. It appears to be working at first then it dies.

[task_result] Child process in wheel 8 wrote to STDOUT: HASH(0x9b22c94
+)
[task_result] Result for cmd: 32240\Kb (1.5%).
[irc_bot_msg] I said '[task_result] Result for cmd: 32240\Kb (1.5%).'

Where I call the code -

my $task = POE::Wheel::Run->new(
        Program => sub { &{$this_code} },
    ProgramArgs => \@program_args,            
    StdoutFilter => POE::Filter::Reference->new(),
    StdinEvent  => 'task_stdin',    # Flushed all data to the child's 
+STDIN.
    StdoutEvent => 'task_result',    # Received data from the child's 
+STDOUT.
    StderrEvent => 'task_debug',    # Received data from the child's S
+TDERR.
#    ErrorEvent  => 'task_error',    # An I/O error occurred.
    CloseEvent  => 'task_close',      # Child closed all output handle
+s.
);
$heap->{task}->{ $task->ID } = $task;

Here's the task_close event handler -

# Child close event
sub task_close {
    my ($heap, $wheel_id) = @_[HEAP, ARG0];
    my $result = $_[ARG0];
    my $child = $heap->{task}->{$wheel_id};
    print "[task_close] Child ", $child->PID, " has finished.\n";
    $child = delete $heap->{task}->{$wheel_id};
}
