Confirmed that db_mode = 3 works as intended however db_mode = 2 results in all 
records disappearing.

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.

Hello,

On 20.12.17 06:28, Daniel W. Graham wrote:
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.
