What happens if the cache memory gets full and we try to set new values?

[Vaibzz]

Hi. I am having a doubt. What happens when cache memory gets full and we try to set new values in it?
Actually I am using this library in a project. But somehow I suspect there is some issue in setting data into the cache. Somehow empty value gets set in the cache. Can this be due to memory issues?
Please help.

It might depend on your machine memory limit. If you reach to the memory boundry, the application crashed.

Greetings. Great utility. Is would be great if we could limit the size of the cache instead or in addition to the expiration time.
