> The code in the User Interceptor that set the last time a user was logged is creating locks.
> In fact threads are trying to acquire a write lock on the user.
> I disabled it for a customer, now we need a generic solution.
> I think to remember that the reason it is done that way is that someone wanted the date when the session stops instead of when it starts.
> Sohil, could you have a look and either:
>  - keep that feature but done in a different way (i don't see how)
>  - record the last login date (instead of last logout) i think this is acceptable in many scenario, anyway the other solution is not perfect neither, most people never log out so it records the session timeout date.
> - move the code to another interceptor so that it can be easily turned off and turn it off by default in 2.7
