[sr-dev] t_unref: REQ_ERR DELAYED should have been caught much earlier

[Juha Heinanen]

i have two lcr gws defined and i call next_gw() followed by t_relay()
first time in route block, but that gw gets drop()ed in branch route:

Apr 18 09:25:35 localhost /usr/sbin/sip-proxy[13916]: INFO: About to relay INVITE <sip:0407058055 at 192.98.100.2:5060>

<-6>

then, in the same route block, i call next_gw() again (which appends the
second gw as a new branch), followed by t_relay(), but get an error that
i have not seen before:

Apr 18 09:25:35 localhost /usr/sbin/sip-proxy[13916]: INFO: About to relay INVITE <sip:0407058055 at 192.98.100.34:5060>

what does that mean?  is it an indication of a tm bug or is there
something wrong what i do in the script as described above?
