[Freeswitch-users] mod_managed - beginner's question about an event listener module

[Rafal Gwizdala]

(...)
one more thing, my module caused an access violation during FS shutdown.
Probably because my event receiver thread wasn't stopped. Is there any
'system shutdown' hook so I could do the cleanup?
