Summary: Error in lcr in function next_gw
Initial Comment:
If the first gateway, got from main route, do not answer at all (we can see
retransmissions), calling function next_gw for searching a next gateway in
failure route cause error:
openser: ERROR: append_branch: max nr of branches exceeded
sip openser: next_gw(): ERROR: do_action failed with return value <-1>
And it is impossible to get next gateway, although it is.
------------------------------------
(config failure_route[1])
if(!next_gw()){
t_reply("503", "Service not available, no more gateways ");
exit;
};
But, if openser is restarted, the problem go away and the function next_gw
works properly for 20-30 minuties (on production platform), and after that
period the problem appears again.
Memory leak problem?

I'm closing this because a possible cause for the problem has not been
identified and no further information has been provided.

is this error message the first one there is in your log file or is there
something before it?
i was reading the code and the above error may happen if you don't
terminate your script after next_gw() returns -1, but keep on calling
next_gw().
i suggest that you insert an xlog statement in your script that is
executed each time next_gw() is called on a request-uri and that tells the
uri and if the result was success or failure.

Thanks,

is
>that next_gw() was called too many times on the same request.
but if i restart openser (I wrote it), there is no problem!! next_gw
answers properly --- for 20 -30 minutes!!! and then the problem appears
again!
----
failure_route[1] {
if (t_check_status("486|487|488|[1-3][0-9][0-9]"))
return;
if(!next_gw()){
t_reply("503", "Service not available, no more gateways ");
!!!!!!!!!!!!!!!!!!!!1here the problem!!
exit;
};
t_on_failure("1");
route(1);
}

i found and fixed two memory leaks in next_gw() function, but they only
appeared in case of internal error, that should never happen. so i doubt
that this helps in your problem.
logical explanation to your error message (max nr of branches exceeded) is
that next_gw() was called too many times on the same request.
