[SR-Users] unregister user when kamailio looses TCP connection.

[Vitaliy Aleksandrov]

Thanks community for all replies.

I did the second try. Result is in the attachment.

This time a did it in the way proposed by Daniel-Constantin Mierla.
All job is done in timer process when it iterates through all 
registrations looking for expired ones.

It works for all database modes except DB_ONLY.

I'm not sure about tcpconn_get() / tcpconn_put() functions. 
tcpconn_get() increments ref counter, but there are several function to 
decrement it: tcpconn_put(), tcpconn_chld_put() and 
atomic_dec_and_test(). When I was looking for examples in other modules 
I saw that tcp_read.c uses tcpconn_chld_put(), but forward.h and 
msg_translator.c uses only tcpconn_get() without decrementing ref 
counter at all.

It would be great if somebody more experienced shed some light on this.
