Hi I have a master Mysql server from where i am replicating other 2 slaves. The issue is one of the slave stops with an error frequently. The error message is below.
Error 'Duplicate entry '1993996' for key 1' on query. Default database: 'ooxadmin_ooxmonitor'.
Query: 'INSERT INTO users_history SET
user_id = '22',
user_last_access = NOW(),
user_status = 'Online',
user_session = 'aa78ee40a941aea26a0e0c10c714b5a9',
user_ip = '126.96.36.199''
I have tried
'SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1' and starting the slave again, then it starts replicating and then stops after a few minutes/hours. I want to know what causes this issue and how to setup replication without this error. My mysql version is 5.0.9.
