What version of POE are you running? I gather from your other email that you are running on Win32.

Having the app work for a minute or so and then hang sounds suspiciously like

Hi,

my session is behaving strange here.  If it was running for a short
amount of time (a few minutes), then it terminates perfectly.  After
running for about 5 minutes though, it won't terminate after sending a
SIGINT to it.

The sigint handler removes all alarms (delays) that have been set.
Posts and yields should not be cleared.  They should be processed and
then the session should terminate.  I did not set any extra references,
aliases or open files.

The application consists of two main loops that get executed by a delay
timer.  It also uses POE::Compononent::Win32::ChangeNotify, if this is
relevant.  It gets shut down though, when the sigint arrives.

The strange thing is that if this /delay-loop/ gets executed probably a
few hundred times, then the session terminates after a sigint.  If it
was running much longer, then it does not terminate.

I was reading this FAQ
<http://poe.perl.org/?POE_FAQ/Why_do_my_sessions_not_stop_on_their_own>
and added a trace refcount.  This is the output after a sigint, if it is
not terminating.

How can I find out what actually keeps the session alive?

I see that there's one event, one extra and one process.  Is there a
more detailed list anywhere?


Thanks,
Andreas
