### Description

The kamailio 5.6.0 segfault on restart

### Troubleshooting

Kamailio sends a Ping Options packet to the registered UA with keepalive functional of usrloc module. When you restart the kamailio with the systemctl restart kamailio command, the kamailio is segfault. In version the 5.5.4 same as in 5.6.0

#### Reproduction

1. Enabled keepalive functional of usrloc module. 2. Registered UA on wss protocol. 3. Restart the kamailio

parameters on usrloc module

``` loadmodule "usrloc.so" modparam("usrloc", "user_column", "username") modparam("usrloc", "contact_column", "contact") modparam("usrloc", "expires_column", "expires") modparam("usrloc", "q_column", "q") modparam("usrloc", "callid_column", "callid") modparam("usrloc", "cseq_column", "cseq") modparam("usrloc", "methods_column", "methods") modparam("usrloc", "flags_column", "flags") modparam("usrloc", "cflags_column", "cflags") modparam("usrloc", "user_agent_column", "user_agent") modparam("usrloc", "received_column", "received") modparam("usrloc", "ruid_column", "ruid") modparam("usrloc", "keepalive_column", "keepalive") modparam("usrloc", "use_domain", 0) modparam("usrloc", "db_url", "DBURL") modparam("usrloc", "db_mode", 1) modparam("usrloc", "matching_mode", 1) modparam("usrloc", "preload", "location") modparam("usrloc", "nat_bflag", FLB_NATB) modparam("usrloc", "handle_lost_tcp", 1) modparam("usrloc", "timer_interval", 10) modparam("usrloc", "version_table", 0) # modparam("usrloc", "ka_mode", 1) modparam("usrloc", "ka_method", "OPTIONS") modparam("usrloc", "ka_from", "sip:keepalive_test@own.domain") modparam("usrloc", "ka_domain", "own.domain") modparam("usrloc", "ka_timeout", 30) modparam("usrloc", "ka_loglevel", 3) ```
