<p>Hello,</p>
<p>to be clear for me: the error messages pop up only when outbound
module is used and only for branches that are routed using
outbound-specific connections?</p>
<p>Cheers,<br>
Daniel<br>

I have a single proxy/registrar mhomed setup and am trying to use outbound
(rather than nathelper) to test a few UACs that seem to maintain their
connection better with outbound. (I am also using the dialog module).
Everything else seems to work properly in light testing, except for the
"qm_free(): BUG" issue, which only pops up when an "outbound" UAC is one of
the branches (the other branches are not using outbound and are always
directly connected on the "internal" side of the mhomed network.
####!define WITH_NAT -- disabled for outbound
#!define WITH_OUTBOUND
#!ifdef WITH_OUTBOUND
modparam("registrar", "outbound_mode", 1)
modparam("registrar", "flow_timer", 25)
#!endif
Snippet of the WITHINDLG route:
# Handle requests within SIP dialogs
route[WITHINDLG] {
if(!has_totag()) return;
# sequential request withing a dialog should
# take the path determined by record-routing
if(loose_route()) {
# dlg_manage() with dlg_match_mode=2
dlg_manage();
#route(DLGURI); -- NAT disabled

I've attached the related routes. Thanks. -A

<pre class="moz-quote-pre" wrap="">Hello,
is it a custom configuration file or simply the default kamailio.cfg
with parts of branch_route enabled/disabled? If it is custom, can you
paste here the content of the branch route that you disable/enable parts
of it and get the error messages?
Overall, seem like trying to (re-)use a terminated transaction or branch.
Cheers,
Daniel
