This is not the only thing happening in the same time but I suspect the following:
1 Some entity is sending a not very well formed REGISTER (without expiration value), here is an example:
REGISTER sip:example.com SIP/2.0.
Via: SIP/2.0/UDP 10.37.145.129;branch=z9hG4bKc5af.bf143451000000000000000000000000.0.
To: <sip:alice@example.com>.
From: <sip:proxy.example.com>;tag=73b08d5bebdaf32004cf12d15b90246a-2710.
CSeq: 10 REGISTER.
Call-ID: 67cff7c9.
Max-Forwards: 70.
Content-Length: 0.
User-Agent: kamailio (4.4.0-dev5 (i386/linux)).
Contact: <sip:alice@proxy.example.com:5060>.
Authorization: Digest username="2291511132",realm="example.com",integrity-protected="auth-done",uri="sip:example.com",nonce="",response="".
.
2 Kamailio receives it and performs a reginfo subscribe on contact header ($ct) for my obscure needs:
reginfo_subscribe("$ct");
3 Kamailio crashes

#!endif
#!ifdef WITH_PUA_USRLOC
modparam("pua_usrloc" , "default_domain" , "SERVER_DOMAIN")
#!endif
I will try with MySQL to see if I get the same results (if issue is related to DBMS).
