Subject: [sr-dev] Crash in s-cscf registrar module<br>
To: Development mailing list of the sip-router project<br>
<<a href="mailto:sr-dev@lists.sip-router.org">sr-dev@lists.sip-router.org</a>><br>
<br>
<br>
Hello,<br>
I am seeing a crash within the latest ims modules using the example<br>
cfg scripts. It also happened in 4.1<br>
<br>
1) The s-cscf receives a request from an application server and runs<br>
'assign_server_unreg' (cfg line 368) because the intended destination<br>
is not registered.<br>
2) The HSS returns an error '5012: Unable to comply' and the suspended<br>
transaction is resumed into the UNREG_SAR_REPLY route (cxdx_sar.c:290)<br>
3) The coredump shows that the AVP lists are nonsensical, so the<br>
action to get $avp(s:saa_return_code) causes a crash.<br>
<br>
Do the avp lists need to be re-initialised from the suspended<br>
transaction, like in the 'success/done' section (cxdx_sar.c:252)?<br>
Maybe someone who is more familiar with this code can shine some light on this?<br>
<br>
Also in this scenario I can't see a code path that will send a<br>
response back to the application server e.g. '480 Temporarily<br>
Unavailable' - Should this be done in the cfg before calling<br>
assign_server_unreg?<br>
<br>
Regards,<br>
Hugh<br>
