[Kamailio-Users] lifetime and TCP connection timeout

[Aymeric Moizard]

Some additionnal information:

I tried several value for tcp_connection_lifetime!

tcp_connection_lifetime = 120  -> close TCP conn after 50 seconds
tcp_connection_lifetime = 300  -> close TCP conn after 90 seconds
tcp_connection_lifetime = 600  -> close TCP conn after 160 seconds

Do I have "tick" issue? Any idea?

I think I'm close to find either a bug or an issue with my kernel?

I got a timer running a route[] for statistics computation, in
case that would change something?

I'm using rtimer module: could this have an impact?
