We're running FS on Solaris 11.3 and it is working perfectly, except that we're unable to restart FS without deleting the TLS registrations from sofia_reg_internal.db.
Our FS version is FreeSWITCH Version 1.9.0+git~20171010T231940Z~5940b04d4e~64bit (git 5940b04 2017-10-10 23:19:40Z 64bit)

Here are the symptoms:
1.    Service stops FS with fs_cli -x "fsctl shutdown now"
2.    FS stops and the service is restarted
3.    FS starts up and fs_cli is working, but ” sofia status” is empty
The console shows:
freeswitch@fs> 2018-02-12 17:06:23.875991 [ERR] sofia.c:3221 Error Creating SIP UA for profile: internal (sip:mod_sofia@123.123.123.123:5060;maddr=123.123.123.123;transport=udp,tcp) ATTEMPT 3 (RETRY IN 5 SEC)

The likely causes for this are:                                                                                                                            
1) Another application is already listening on the specified address.                                                                                      
2) The IP the profile is attempting to bind to is not local to this system.

Note: the IP is correct and nothing is listening on the port.

4.    Next we stop FS and restart
This time the console shows:

5.    sqlite3 sofia_reg_internal.db "DELETE from sip_registrations WHERE status LIKE '%TLS%'"
6.    FS starts normally


Here is a registration (non-TLS) that doesn’t break sofia:
