[SR-Users] possible bug with dialog module

[Kelvin Chua]

yeah lots of traffic.
so there's no way of telling whether that particular BYE caused the crashed
or not.
unless i enable debug for the server.

besides, you're right it might just be a simple case of receiving a BYE for
an expired
dialog or something, doesn't seem too fishy at all. i wonder if anybody from
the list
is also experiencing this?
