[SR-Users] kamailio 522 S-CSCF failing to start

[Martin W Woscek]

Hello,
There are times that our S-CSCF module just wont start. I’ve tried correlating the issue with some operation such as not de-registering an IMS client (Boghe or imsdroid) prior to shutting down the Kamailio server.  But this isn’t always the case.  Being that we are running this an a Ubuntu Virtual Machine, simply overwriting the image with a backed up VM is the temporary solution.

I’ve dropped and created the db for S (kamdbctl) and rearranged the order of loading the presence module with same result.

Status of the S-CSCF daemon on failure to start:

Any insight is appreciated.
