Hi Henning,

The following are the mysql related logging I see on initial spinup of the Kamailio 5.2.2 IMS VM: Jun 16 06:15:28 ubuntu systemd[1]: Starting MySQL Community Server...

Hello,

the error message below is from the DB startup version check. So do you have sometimes DB errors on this virtual machine?

Cheers,

Henning

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.

Any insight is appreciated.
