[SR-Users] GDB debugging Kamailio 5.2.2 IMS authorization failed by the SCSCF

[Woscek, Martin W.]

Hi,

Looking for some advice running the debugger and setting breakpoints in Kamailio modules such as the SCSCF.
Example: We were trying to watch the authenticate() function:
714 int authenticate(struct sip_msg* msg, char* _realm, char* str2, int is_proxy_auth) {

Our Kamailio 5.2.2 code was compiled and linked from source with the -g option already enabled by default.

We also dropped our Workers to 1 from 16 in the scscf.xml file for the SCSCF to limit the thread count and get the following list of threads below:
We tried the first cdp threads: 8462, 8463, and 8464 and while we could set a break point at line 714 for the authenticate() function, it didn't actually break there at all.

Question:
What pid will we use to catch the authenticate() called during an initial registration from a boghe client?
Anything special we may be missing, gdb related or Kamailio settings?
