In an heavy loaded environment, this can be achieve in a few seconds easily, this will reload your rails app just too often which will slow down your server. Hi Vitaly,

I18n.locale is just one examples, but there are many plugins and gems that leak symbols. So I prefer to simply limit the number of requests any given application server instance can provess. For example, when using Fusion Passenger I set PassengerMaxRequests to something like 200-500, so that I'm sure it can't leak too much during its lifetime.
