Finally our twitterized version of 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


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
