No method error after upgrade from 2.1 to 2.3

Hi,
I am trying to upgrade my existing 2.1 rails application to 2.3.3.
Everything works fine in 2.1.
Now after the upgrading I get either “stack level too deep” errors or
“undefined method errors” if a I have requests in parallel or shortly
after another (like I press f5 quickly twice).
The first request works fine, the second raises this error.

Just to be clear on this. The method exists, and everything works fine
if I just hit f5 once. It ONLY happens if I hit f5 twice.

Processing UserStatsController#total_raised (for 127.0.0.1 at 2009-09-09

probably issues with the code reloading stuff (if this is happening in
development) or the code preloading (if this is happening in
production)
For the former errant requires are often a cause. For the latter this
can be due to the fact that models are now loaded before the code at
the bottom of initializer.rb is run

Hi Fred,
The problem occurs on both environments. The method is defined in the
User model, so how can I change this behavior (or my code) to circumvent
this.

Shall I look for all ‘require …’ in config/initializers to see if they
are causing the problem?

thanks

They are only problematic if they require code in your app that could
be autoloaded. Also worth seeing if there isn’t a method or column
in your model that has since become a name used by rails.
