Yes this happens in a testing environment..
I got your point, we saved after t-relay to send the message faster as db save
can cause delay.
We will make the changes as per your suggestion .
Thanks

Hello,
is any particular reason to do the processing after t_relay() ? You can do
the save before, since it is the same register message.
Also, are you getting this in a testing environment while using tools like
sipp to simulate traffic?
Starting with 3.0, the AVPs (which are associated with the message and
transaction in this case) become available in onreply_route[3] (in 1.x that
was a config option for tm module), so if it is fast reply, it my happen that
the avps are no longer available in the script after t_relay().
As a recommended rule, it is better to avoid using avps after t_relay() -
this function creates the transaction and forwards the message. From there
on, the avps are in the hands of tm module, which moves them to onreply_route
or failure_route, depending on your config file.
Cheers,
Daniel

Hi Daniel,
Please find the code and corresponding error trace. This happens only for 1
subscriber randomly out of 2000 subscribers. This can be reproduced
consistently also.

Hello,
it is not clear for me what you tried to do. Can you paste here the parts of
the config file that are relevant for the case? Do you relay the REGISTER?
Cheers,

Hi All,
On register we store the contact in an avp variable and do a t_relay().
After t_relay() the $avp variable becomes null.
I printed the value before after t_relay() to determine this behavior.
This happens only on registration load test around 2000 subcribers with ( 4
REGISTER/sec). This happens only for one subscriber out of 2000
subscribers.
I did the similar test with $var and its working fine.
Anybody observed similar behavior with avp? This was working in kamailio
1.4 version. We did the upgrade recently to 3.1.0 and started observing
this issue.
How do we debug this issue.?
Thanks
Jijo
