Is it possible that clients whose records disappear roam between servers? I.e.
register with the active server, but then registers with a standby server
while the active one is still up and running?

Yes, to your first question, most records originally
written by the active
server disappear. Only way to restore all records to the location table is
taking standby servers offline and restart Kamailio on active server. If a
restart is not performed records wont reappear in table. db_mode is 2
Database is replication is active passive.

Kamailio Servers + Location Table
Hello,

When multiple Kamailio servers are using the same database with different
server_id's (one active the rest standby in this test), records disappear
and are no longer tracked in location database table.
Some entries remain, but it never populates to the normal amount unless only
one server is using the database. I couldn't figure out the proper picture
of what happens based on the above ... some questions:
- only one server (the active) writes to database, with its own id (other
servers have different ids), after a while some records written by the
active server disappear?
- is db_mode=3? If not, what value.
- is there any replication at database layer?
Cheers,
Daniel
Anyone run into this before? Happened with 5.0 and is happening with 5.1.
