[Kamailio-Users] lifetime and TCP connection timeout

[Klaus Darilion]

Hi Aymeric!

I justed tested on one of my proxies (kamailio 1.5) and with the default 
setting (120s) it closes TCP connection always after 131 seconds - strange.

If I set to 30, the connection will be closed after 41 seconds.
If I set to 300, the connection will be closed after 311 seconds.

Looks like in my case there are always 11 seconds added (maybe some 
other timeouts before the connection enters the "idle" state in the TCP 
handler).

Anyway, that does not answer the problems you are experiencing.

regards
klaus
