Problem:
The mysql db issues with the scscf db include: table version, disappearing impu and/or UE data retained in tables when none are registered
Workarround:
In order to get over those various mysql issues listed causing the S-CSCF not to come up properly as boot up,
/etc/init.d/kamailio_scscf
..
case "$1" in
start|debug)
mysql -u root --database=scscf < /etc/kamailio/ims_databases/scscf.sql
The S-CSCF has been stable and dependable on each boot.

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

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