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?

This just means that Kamailio has received a BYE thtat doesn't match
with an existing dialog. Perhaps the dialog expired, a previous BYE
from the other side was already received or kamailio was restarted and
doesn't keep the dialogs info in database.

Are you sure that the folowing log lines occur due to the previous BYE
line? has the server lot of traffic?
