(Reposting from sr-dev because, in retrospect, it makes more sense here.)
Does anyone know of any issues running usrloc with DB backing ('location') in a multi-master DB-replicated environment? I am referring to plain usrloc, not p_usrloc.
I have such an environment set up with db_mode = 1 (immediate write-through) and have run into a problem where Kamailio occasionally stops writing to the location table for no apparent reason. I am wondering if this is because another Kamailio instance bound to the secondary replica is performing a DB sync as well, and at some point they collide in some sort of race condition. Would db_mode 2 fix? Would anything fix? Is this even the problem?
