Hello, I've got few freeswitch servers sharing same data base placed on Percona Galera cluster. Accidentally I observe deadlocks - example below: 2015-01-13T21:51:23.531909+00:00 fs1dev freeswitch[3357]: 2015-01-13 21:51:22.414677 [ERR] switch_core_sqldb.c:581 ODBC SQL ERR [STATE: HY000 CODE 1213 ERROR: [unixODBC][MySQL][ODBC 5.1 Driver][mysqld-5.6.15-63.0]Deadlock found when trying to get lock; try restarting transaction#012]#012update sip_authentication set expires='1421185972',last_nc=15 where nonce='6544a9e0-9b6d-11e4-9010-a17af9ccfef5 I've found that in case of Percona Galera cluster deadlocks are something that could happen: http://www.percona.com/blog/2012/08/17/percona-xtradb-cluster-multi-node-wri... Now I have option to set automatic retry on Percona Galera cluster (which is a bit dangerous since freeswitch won't be aware of that there was some problem with transaction) but it's not a best choice. I wonder if freeswich do retry after such error? - that would be the best option. -- Pozdrawiam Wojciech Matys
