I indeed see the same spiral messages in the logs as well:
Jan 22 14:50:33 sip /usr/sbin/kamailio[14084]: DEBUG: dialog

'035a329653a80be399f7b45e6c734415@192.168.149.126' found, must be a
spiraled request

I think the problem with 4.2.2. is the following:
After dialog cleanup code is not executed after script exit. Thus, if
the dialog is created without generating a transaction, e.g.:
...
dialog_manage();
... some checks
sl_send_reply();
exit;
the dialog is created, but not destroyed after exit. Thus, next time a
request with identical dialog IDs (e.g the second INVITE after
authentication) is received, Kamailio finds the un-destroyed dialog and
falsely think this message belongs to a spiraled request and thus does
not register the tm_callbacks for the responses. Thus, the dialog stays
in state 1 forever.
Probably there are 2 bugs:
1. The dialog callbacks are not executed on script exit (this works
fine
in Kamailio 4.1.7)
2. The spiral detection code is buggy. Just because a dialog exists is
not a proof for a spiral. In fact, a request with only 1 Via header can
never be a spiraled request.

Klaus,
Yes, that solves the problem here as well.
Thanks,

Hi Jan!
I replaced dlg_manage with setflag(dialog flag). This way the dialog
is
created only when a transaction is created. It solved my problems.

Nice, I have the same problem after upgrading from 4.1.7 to 4.2.2.

..... in my case it seems the dialog callbacks are not executed for
responses ... I am still debugging .....

Hi All,
I'm running into a issue with the dialog module since the upgrade
from
4.2.1 to 4.2.2. I use the dialog module to add extra vars to the
cdr's
generated by the ACC module.
I use the following config:
# ----- dialog params -----
modparam("dialog", "enable_stats", 1)
modparam("dialog", "dlg_match_mode", 1)
modparam("dialog", "dlg_flag", FLT_DLG)
modparam("dialog", "rr_param", "did")
modparam("dialog", "wait_ack", 1)
# Create dialog
if (method=="INVITE") {
# Create Dialog
dlg_manage();
# Add test dialog var
$dlg_var(src_ua) = $hdr(User-Agent);
}
This seems to work fine on kamailio 4.2.1 but after the upgrade i
see
the following errors in the logs:
Jan 22 13:16:57 sip /usr/sbin/kamailio[2773]: CRITICAL: dialog

If i'm correct "bogus event 6 in state 1" indicates that a ACK whas
received while the dialog still was in unconfirmed state. Should i
catch
the 200 OK on the INVITE to update the dialog?
Thanks,
Jan Hazenberg
