[SR-Users] MySql Deadlock errors in Presence updates but db_mode set to 0

Hi there My config is a primary:secondary DNS srv failover Kamailio 5.2 setup using DMQ for syncing Location, Presence, HTable etc. For Presence db_mode set to 0 on both servers. This works fine on the primary server but on the secondary server I get repeated mysql deadlock errors. I seem to be missing a config setting to turn off db_mode fully for presence but I cant see where. Error seems to occur on message-summary updates from master that are being replicated to slave via DMQ.
