Thank you for any help you might provide. This is keeping me awake nights...
Mysql::Error in <mycontroller>#<mymethod> Lost connection to MySQL server during query RAILS_ROOT: <mypath> Application Trace c:/ruby/lib/ruby/site_ruby/1.8/mysql.rb:1116:in `write` ...
This error has come up intermittently but often for many months... It is keeping us from rolling out a RoR system. I've devoted a day a week for the past two months to try to fix it without any success. I've fiddled with: MySQL parameters -- no effect from High values for all timeouts environment.rb -- no effect from ActiveRecord::Base.connection.instance_eval {@connection.reconnect = true} database.yml -- no effect from timeout: 8000 reconnect: true
The problem doesn't happen with batch programs -- only with Rails.
It happens with about one transaction in twenty.
The problem doesn't seem to correlate with database load, or idle time, or anything else.
Any ideas or suggestions? Any suggestions on how to collect good data on what's causing this?
