Hello,
I run kamailio 3.0.3 with location table stored in database (PostgreSQL 8.4.2)
with db_mode 2 (write-back) and upon kamailio restart some contacts from
database are loaded incorrectly. Messages for those contacts are routed to
invalid IP addresses.
After some debugging I figured out that it happens only for contacts which
"received" column value is null. For those contacts value is filled from
previously loaded contact having non-null value in "received" column.
Here is sample debug, which shows contact (row #97 in result set) with IP
10.3.71.1 is later used for contact without "received" value (row #172):

To make things clear, all rows after row #97 had "received" value null, and
row #172 was UA I ran tests on... in the other words contact with null
"received" value is filled with previous non-null value as long next non-null
row is fetched from DB and following null contacts are filled with its value
and so on.
When the contact having invalid "registered" re-register it will overwrite
value in memory and calls are routed to proper IP address. This query is sent
to database then:
db_postgres [km_dbase.c:149]: 0x888e00 PQsendQuery(update location set
expires='2010-09-16 00:30:58',q=-1.00
,cseq=103,flags=0,cflags=0,user_agent='Asterisk
SIPXSIP',received=NULL,path=NULL,socket='udp:80.200.1.100:5
060',methods=NULL,last_modified='2010-09-16 00:20:58' where
username='222333444' AND contact='sip:222333444@195.70.1.200' AND
callid='0fc6692b6570aaac04b3c85a3b9496c0(a)sipxsip.cz')
I've also checked status of this record in usrloc by "kamctl ul show"...
both
before and after kamailio restart state was CS_SYNC.
Is this bug or should I somehow force kamailio to store "received" into
database?
Kind Regards,
Jan Klepal
