so, after all seams to be a scripting problem. try to remove
t_lookup_request() and t_check_trans() from your script ( t_relay() will
detect the retransmissions anyhow). If you still get the error, please
send me the script - it will spare a lot of time.
regards,

No, the problem remain.
When a retrasmission arrives, both t_lookup_request() and
t_check_trans() are TRUE, and the following error appears:
Dec 8 16:44:15 eowyn OpenSER[7103]: ERROR: t_newtran: transaction
already in process 0x512a22e0
Dec 8 16:44:15 eowyn OpenSER[7103]: ERROR: sl_reply_error used: I'm
terribly sorry, server error occurred (1/SL)
Bye.

Hi Federico,
I'm afraid you have a script error - you called twice some
functions which create transactions...The error is generate most
probably by t_relay() which found the transaction already created
in the script (maybe via t_newtran).
Yes, I know it.
It is the UAC module that create a transaction (I don't know if in
any case or only in some cases).
the uac module does not create a transaction - uac_replace_from()
performs just text mangling and installs some hooks.
You are right, this problem doesn't seem to be related to the UAC
module (I was confused by the previous AVPs vanishing bug).
Anyway, when a retrasmission of an INVITE reaches the t_relay()
function, the following error appear:
Dec 8 14:56:18 eowyn OpenSER[21824]: ERROR: t_newtran: transaction
already in process 0x50132480
Dec 8 14:56:18 eowyn OpenSER[21824]: ERROR: sl_reply_error used:
I'm terribly sorry, server error occurred (1/SL)
And the UAC closes the call (because of the 500 error)!
Please note that there is no t_newtran() in the entire script, and
the problem occours only with the retrasmissions!
What is the supposed way to avoid this?
Thanks.
So when the message arrives at the classic t_relay() part of the
script, I cannot know if a transactionis is already established.
To be able to help, please send the script (privately, if
necessary) to take a look.
If you still think that there is problem somewhere, I will send
the script to you...
Bye.
P.S.
I sent a similar question at "[EMAIL PROTECTED]", but still no
usefull reply...

Hi Frederico,
that's good..one more down....
Well.... the AVPs are no more disappearing, but I still have
some problem with the reinvites...
It seems that uac_replace_from() creates a transaction when an
INVITE retrasmission is received. Infact in that case the
following errors are logged for the retrasmitted INVITEs:
Dec 5 18:49:25 eowyn OpenSER[5654]: ERROR: t_newtran:
transaction already in process 0x502a56f8
Dec 5 18:49:25 eowyn OpenSER[5654]: ERROR: sl_reply_error used:
I'm terribly sorry, server error occurred (1/SL)
This is generated by this standard code:
if ( !t_relay() ) {
sl_reply_error();
}
I thought that I could find the retrasmissions (with the
t_lookup_request() function) and use the t_forward_nonack_uri()
function in that case, but I got the following error:
Dec 5 18:47:29 eowyn OpenSER[26647]: ERROR:tm:t_forward_nonack:
no branch for forwarding
Obviously, I have not enought undestanding of TM functions and
transactions in general.
So, the question is: can anybody post a correct fragment of
script code that relay a message, correctly handling
retrasmissions?
Otherwise, could I simply discard retrasmissions (with a simple
exit)?
And how I can recognize retrasmissions? Is t_lookup_request()
the correct function for a test?
Thanks.

Hi Cesc,
right!! as the transaction list is set all the time
(disregarding the presence of callbacks), it should be also
unset all the time....
This solves the bug of the AVPs disappearing with retrasmitted
INVITES too!!!
Bogdan, now you can remove that bug from the ones to search
for...
Thank you Cesc.
