---------- Forwarded message ---------- From: Hugh Waite hugh.waite@crocodile-rcs.com Date: 2013/12/15 Subject: [sr-dev] Crash in s-cscf registrar module To: Development mailing list of the sip-router project sr-dev@lists.sip-router.org
Hello, I am seeing a crash within the latest ims modules using the example cfg scripts. It also happened in 4.1
- The s-cscf receives a request from an application server and runs
'assign_server_unreg' (cfg line 368) because the intended destination is not registered. 2) The HSS returns an error '5012: Unable to comply' and the suspended transaction is resumed into the UNREG_SAR_REPLY route (cxdx_sar.c:290) 3) The coredump shows that the AVP lists are nonsensical, so the action to get $avp(s:saa_return_code) causes a crash.
Do the avp lists need to be re-initialised from the suspended transaction, like in the 'success/done' section (cxdx_sar.c:252)? Maybe someone who is more familiar with this code can shine some light on this?
Also in this scenario I can't see a code path that will send a response back to the application server e.g. '480 Temporarily Unavailable' - Should this be done in the cfg before calling assign_server_unreg?
Regards, Hugh
