Hi,

Thanks for you answer. It helps.

I tried different values but get stuck to low. I am stopping investigating on
this issue.

I will impatiently wait for the v3. By any chance, do you have an idea of the
release date or even of the first beta date ?

In the mean time, I am thinking of using Nagios with MySQL (instead of default
files) which will allow me to update the database directly. Do you think this
could be effective ?

Thanks again.
