Looking at the source code, it seems the extra_data is not set. But that does not explain
why $conid is <null> when tcp:closed event route is triggered.

I am running latest kamailio 5.6.2 and attempting to
detect tcp/tls connection being disconnected or closed using tcpops module. As suggested
in tcpops documentation at
https://www.kamailio.org/docs/modules/devel/modules/tcpops.html, registered event routes
as below.
event_route[tcp:closed] {
xlog("L_INFO", "$proto connection closed ($conid)\n");
}
event_route[tcp:timeout] {
xlog("L_INFO", "$proto connection timed out ($conid)\n");
}
event_route[tcp:reset] {
xlog("L_INFO", "$proto connection reset by peer ($conid)\n");
}
Now it is observed that the event route is being called but the $conid is not set. The
logs show the below log statements and extra data is (nil).

Can anyone provide any pointers on what I am missing?
Thanks in advance.
