> The dispersion on connections expirations in the C++ native client works in such a way that it adds a dispersion (variance) between -9% and 9% over the time for a connection to expire due to load-conditioning so that, in the event of having many connections being created at the same, they do not expire at the right exact time.
> Nevertheless, the current implementation has two problems:
> - The randomness of the variance depends on the current time in seconds. As a result, for connections created in the same second, the variance will be the same and, therefore, the expiration time too.
> - The randomness is created using the C standard's library "rand()" function which is considered not secure.
> It is recommended to change the library used to generate the random variance to a secure one and also to make sure that for the time in seconds it does not return the same variance.
