POE has fantastic facilities to tracing its own inner workings including sessions that might be sticking around. Take a look in POE::Kernel for turning on some of this information. From my own experience on debugging memory leaks in POE applications it is typically two places: sessions that don't get GC'd (zombies), and the heaps in those sessions with ever growing numbers of keys. After that, you might end up with a cyclic reference somewhere that doesn't get cleaned up, so you can use Devel::Cycle. Without looking the code, it is difficult to give you any more pointers. -- Nicholas Perez XMPP/Email: n...@nickandperla.net https://metacpan.org/author/NPEREZ http://github.com/nperez
