If master doesn't replicate Annotate_rows_log_event to slave, mi->master_log_pos is incorrect (less than log_pos-on-master to sizeof(Annotate_rows_log_event) that weren't sent from master to slave). 3) After slave_net_timeout slave reconnects to master and sends mi->master_log_pos to it. As a result, master tries to read event from its log from incorrect position. Possible fixes: 1) always replicate Annotate_rows_log_event from master to slave. If you do this, option "--replicate_annotate_rows_events" doesn't have sense (always true) and should be removed 2) fix the Master Dump Thread - when "--replicate_annotate_rows_events" disabled or slave run with "--log_slave_updates=0", master should notify slave about skipped events (probably as filtered event or send Rotate_log_event )- I don't sure what this is possible or correct fix (just idea)]]> bug Oleg Tsarev added bug attachment added Oleg Tsarev attachment removed Oleg Tsarev attachment added Oleg Tsarev attachment added Oleg Tsarev nominated for series Oleg Tsarev bug task added Oleg Tsarev bug task added Oleg Tsarev percona-server: assignee Oleg Tsarev percona-server: status Oleg Tsarev percona-server/rnt-5.1: status Oleg Tsarev percona-server/rnt-5.1: assignee Oleg Tsarev percona-server: importance Oleg Tsarev percona-server/rnt-5.1: importance Oleg Tsarev tags Oleg Tsarev maria: status Kristian Nielsen maria: status Kristian Nielsen maria: assignee Kristian Nielsen branch linked Launchpad Janitor percona-server/rnt-5.1: status Oleg Tsarev percona-server: status Oleg Tsarev branch unlinked Alexey Kopytov percona-server: assignee Alexey Kopytov percona-server/rnt-5.1: assignee Alexey Kopytov percona-server: status Alexey Kopytov percona-server/rnt-5.1: status Alexey Kopytov percona-server: assignee Stewart Smith percona-server/rnt-5.1: assignee Stewart Smith percona-server: status Stewart Smith percona-server/rnt-5.1: status Stewart Smith percona-server: status Oleg Tsarev percona-server/rnt-5.1: status Oleg Tsarev Oleg Tsarev Oleg Tsarev Oleg Tsarev Kristian Nielsen LPexportBug872754_unworkable_annotate_rows_event.tar LPexportBug872754_unworkable_replicate_annotate_rows_events.tar
