Hi,
I have a feeling that this patch creates a big opportunity for closing
wrong connections.
Lets imagine the situation when you have a contact with the tcpconn_id=X
and this contact wasn't refreshed by a UA in time. When proposed option
is enabled kamailio will close a connection with ID = X at the next
timer run. But we have no guarantee that ID = X is still identifies
connection we want to close because this connection could be closed
before timer run and then its ID reused by another client.
Hi,
I want to propose a patch to usrloc:
https://github.com/kamailio/kamailio/commit/14852a98ed46b7a88c92bff31c319d2…
this patch adds a new parameter, close_expired_tcp, that makes usrloc
request the main TCP process to end the connections of expired
registrations (assuming 1 connection = 1 contact).
It enables to release resources on the system ASAP, in the event of a
lost connection (e.g. when clients are on mobile networks).
Any thoughts?
Cheers,
