Hi, I’ve setup PXC on a three node system. At moment, I’ve disabled 2 nodes so only the primary node is active. In this configuration I can’t figure out why too often the system load is up to 20… The result is that the server doesn’t accept connections anymore and all queries dies with error like this
‘ActiveRecord::StatementInvalid: Mysql::Error: MySQL server has gone away: SELECT
multimedia_files WHERE (
id = ‘115364’) AND (
multimedia_files.author_id = 26737) LIMIT 1’
With standard mysql server, I never had this kind of issue.
Any hints to debug this?
