Running Jruby / Rails 2.2 on Solaris 10 x86 with SUN MySQL Enterprise
and seeing intermittent timeouts via ActiveRecord (Connection Lost, No
Message, etc). we have enabled the proper connection pooling in the
servlet container via DBCP and have also tuned mysql wait_timeout but
still receiving these via ActiveRecord. We even added in an
initializer to after_dispatch verify_all_connections.
Has anyone encountered any issues similar to this on this
environment? This appears to be specific to either solaris or MySQL
enterprise not playing nice with the Rails connection pool and we are
trying to nail it down.
