I have noticed a consistent difference between the location records OpenSER has cached and those stored in the database. e.g. openserctl ul show --brief database engine 'MYSQL' loaded Control engine 'FIFO' loaded entering fifo_cmd ul_dump brief Domain:: location table=512 records=19 max_slot=2 Compared to: select count(*) from ser.location; +----------+ | count(*) | +----------+ | 10 | +----------+ 1 row in set (0.00 sec) This difference is consistent over time. When I look at the database logs OpenSER is trying to update an existing record in the database which, for some reason, doesn't exist. Our config has the following relevant parameters modparam("usrloc", "db_mode", 2) Openser 1.3.2 Any thoughts on how to prevent this circumstance from occurring and how to synchronise the cache with the db in an orderly manner? I had thought that after 120 seconds (timer_interval default)this would happen but it doesn't seem to. Any advice appreciated. Regards Cameron
