Finally our twitterized version of psspy.se is ready. But! When in production – read with many connection – the memcached get overloaded by not closed connections and on 1024 it says
“accept(): Too many open file” and memcached dies.
After 1 day investigating the problem we have found that the following line in the initializers is causing the problem
RAILS_DEFAULT_LOGGER.level = Logger::DEBUG
We havent investigating deeper but when commenting this line everything works fine.
We have tested with Rails 2.3.2 and 2.3.3 with memcache-client-1.7.4
